Best product for logging in market

5.0 6 years ago

Comments: I would recommend logdna to everyone. It's pricing, feature parity and support are best.

Pros:

We have tried many logging solutions out there in the market, but logdna was the cheapest, simple and best solution out there for logging. It has good support for different platforms like cloud, kubernetes and hosted machines. The setup is very simple for even a beginner and UI is very intuitive. It has all the required features for logging. The search and tags functionality has reduced a lot of pain of debugging. The support channel is very active. I have got the solution to all my problems quickly. The alerting feature is very useful in case our service goes down or misbehaves. It supports mails, slack and webhook which we use to automatically restart our server.

Cons:

We can't set per service based logging limit. There are not many colour options for different logs.

LogDNA

5.0 3 years ago

Comments: Our overall experience with LogDNA has been brilliant. While we've looked at other solutions since using LogDNA, we've never really had any desire to leave. LogDNA does everything we need it to do and will continue to serve us well into the future.

Pros:

The ease of use at being able to direct logs from servers in 3 different locations, plus logs from various AWS servers, being able to view more than one of these logs at once, in time order and start from a specific time has made debugging much easier than the past, and then being able to be notified about specific errors as quickly as we think is right. We are now, more often than previously, able to follow the paper trail to see how a certain bug arose without needing to contact the end customer

Cons:

Sometimes the search/filter bar can be quite cumbersome to use, with certain string matches working, even though LogDNA says it shouldn't, and then other string matches, that should work as expected not to work without notice. You can often get these to work after a bit of tweaking and regex work, but it can take some effort at times

We loved how easy it was to get started, but we hit some pain points as we used it more heavily.

3.0 7 years ago

Comments: We were able to get up and running logging centrally from Kubernetes, and it got us through at least one software MVP. Kudos to the team, there just were too many rough spots to move our entire logging infrastructure over to LogDNA.

Pros:

- The Kubernetes integration was fantastic, it was easy to get set up - The pricing was very reasonable

Cons:

- We wanted a single account for our team to make billing easier, but we had no way to segregate "Views" on the left sidebar. We needed some way to have per-cluster views/searches, otherwise it would be very difficult to navigate. - We found we could not trust the "Live" view after clicking around in the UI for a little bit, or leaving it running for a while. We couldn't pinpoint what made it stop updating correctly, but we often had to do a full refresh of the page to see the latest logs, after which we would be inundated with logs that we had missed and it was hard to find our place again.

LogDNA is the perfect tool for someone who just needs to aggregate all of their logs into one place

5.0 7 years ago

Pros:

Not only is LogDNA incredibly simple to setup and use, but it doesn't overwhelm you with features. It does one thing really well: logging. Also, LogDNA is very affordable compared to the alternatives (most of which have lots of features I don't want). LogDNA is a simple product, but it fills a niche that no one else does as simply or elegantly.

Cons:

Nothing! LogDNA is exactly what I want it to be. The only thing that's slightly annoying is that their search doesn't do partial string matching very well, but it's really not that hard to type out the whole search string :)

Customer support was very fast and accurate for what was requested.

4.0 7 years ago

Comments: Detailed insight to specific log items.

Pros:

I like that you can filter quickly and get to the specific pod, time, filter, app. I also like the statistics and is integrated well w/ python logger library w/ the filters. I like that I can access the logs from anywhere.

Cons:

Limit of 30days history for our account. Timestamps need to be converted and not as user friendly. I would like to more visibility on all it's capabilities like ContextFilter was interesting and discovered recently.

Good JSON logging and searching tool

4.0 6 years ago

Pros:

LogDNA does lots right. JSON log ingestion, powerful and fast searching, live tailing, and log analytics. It also archives to an S3 bucket, and has a great slack integration

Cons:

Some reliability concerns a while back, but it looks like they have since been resolved. They need to be mindful about pushing out changes that could affect someone else's logs. Be weary and keep another copy of your logs just incase things go awry.

Hands down the best logging tool I've used.

5.0 7 years ago

Pros:

Love the "view in context" feature, incredibly helpful for our team to quickly diagnose issues and troubleshoot.

Cons:

Lacks alerts for the time-being. Some of the user interface components need a bit of tweaking, but everything is being improved rapidly.

Great Product

5.0 6 years ago

Comments: It was great. The team is easy to work with and they have a great product.

Pros:

Extremely easy to use and does everything you need from a product like this

Cons:

Honestly there was not much. For our use case, we really didn't have anything that we needed it to do.

Best cloud logging system I've used

5.0 6 years ago

Pros:

Easy to set up. Both the Python and Kubernetes drivers are simple, lean, and efficient. The web UI is beautiful and fast. Much more useful out of the box than a standard ELK stack. Can get a lot of benefit even in the inexpensive usage plan.

Cons:

Feature development seems to prioritize mainly around enterprise customers, so small quality-of-life updates are taking a while.

Didn't Think I Would Ever *Love* a Logging Tool

5.0 6 years ago

Pros:

I didn't think I would ever rave about a logging tool, but after sitting through a power-user webinar and using LogDNA, I cannot say enough good things about it. We have beautiful logging views so I can instantly research transactions and events in seconds at a detailed or high-level view. There are things that I anticipate taking a long time or being a headache that turn into a few simple clicks since all the data is accessible in LogDNA.

Cons:

Our team hasn't been consistent in our logging strategy which LogDNA reveals when sifting through different transactions. I also did not know about a lot of the things I could do with the tool until sitting through the 30 - 40 minute webinar.

Title for my review? Huh?

4.0 5 years ago

Comments: We make software robots/chatbots. We don't store conversation transcripts inside of our primary database because we don't want to store those transcripts forever nor add the load to our primary database and app. So we use LogDNA to store all of those transcripts and when errors occur we can pull them up via LogDNA and debug what happened.

Pros:

The interface is quite nice. It is also priced well for high volume. Lastly, it integrates well with other platforms, in particular the Heroku setup is really nice.

Cons:

* The indexing lag lately has been a bit high. Sometimes we get alerted to errors in Slack from our apps and it takes a few minutes before we can read the logs to see what happened. * The search is a little finicky. It'd be great if we could toggle between full text searching and searching using special characters so we didn't have to escape special characters all the time. * It's awesome that LogDNA serves as a single store for all app logs. However the UI for selecting which apps to display and switching between them feels clunky.

LogDNA makes logging fun and easy!

5.0 6 years ago

Pros:

After struggling for years with tail-ing the logfiles of our servers, some genius told me that I should have a look at LogDNA. With their low pricing, I could hardly imagine that they offered quality software. But they do! Once setup at the server, it's easy to create filters (based on server, process, tag or level) to create custom views. So, for example, you can set a view to show all log entries from an error level for a certain process. On top of that, you can also create alarms for views to receive notifications at a certain treshold.

Cons:

For 99% it does what I expect it to do. The only downside over the past years was that occasionally it was a bit slowish with realtime live updates. But most of the time it's pretty fast.

Best tool I've ever used for logging. It just makes sense!

5.0 7 years ago

Pros:

We've used a few other logging tools before, and still struggled with debugging our webapp on multiple servers. Then we found LogDNA, and decided to give it a try. Wow! It's so simple to install, we were up and running within a few minutes. The user interface is clean and intuitive. It's really easy to search keywords (even excluding terms), and jump to timeframes in your own local timezone. You can even type in 10 hours ago and it just works by jumping to the log line with a highlighted marker. It's saved us so much time when diagnosing a problem, tuning our app/server performance, and even when reviewing the logs to predict trends. I also love the alerts and integration with email, Slack, PagerDuty, and even your own Webhook. With a couple of clicks, you can set up the notification rules to trigger an alert. With LogDNA, we always know what's going on at every level throughout the stack.

Cons:

You can't customize the colors for log levels. Although they have a few preset themes to choose from, you can't fully customize it. For example, it's easy to see the Error level highlighted in red, but for the remaining log levels such as Info, Notice, Warning, Fatal, etc., the colors are the same so you can't quickly skim the logs without reading it.

DNA of your product!

4.0 6 years ago

Pros:

1. json log ingestion. We were logging our application logs in json formats and when we were looking for the application it fit into it. 2. S3 back up. Sometime we need to search for the older logs and it helps to get it from there. 3. Search. The advanced search really help us to get what we exactly want it. And we go the context quickly(using switch to context) and it really a cool and handy feature to use. 4. Dashboard. Some time out applications misbehaves and flood the logs. It is super easy to find the service using the dashboard by seeing the log ingestion rate. And we use 50s of services.

Cons:

In the recent release, there is some problem with the search it seems. Getting irrelevant logs

Great, except for repeated issues with log ingestion (remote syslog)

4.0 7 years ago

Pros:

User interface is top notch. So much better than most competitors I've evaluated (which is quite a few actually). Saved views, quick searches and view context functions makes this a joy to use.

Cons:

Two things are blocking our expanded usage of LogDNA for our much bigger product & team: 1. Reliability. The repeated issues with the remote syslog log ingestion is just not acceptable. I've contacted support about it before, but I won't bother again until it seriously improves. We have to restart at least one logspout container each 1-2 weeks. And there ARE NO ALERTS that things aren't ingesting properly. Basically I don't trust that all log data is there anymore. 2. Pricing. The pricing is great for small log volumes and short durations (as for the product we've migrated to LogDNA). But for slightly larger volumes (say 50 GB) or longer storage (14-30 days), the pricing is too high compared to competitive offerings (from e.g. Logentries). Fewer plans (3 + free) with clear separation by features would be clearer. Costs should increase linearly with storage volume AND retention length (multiplied). This would make pricing clear and logical, instead of using "minimum charges" which is just annoying and stops us from increasing our usage until we reach that threshold. I completely understand the need to raise prices for more value delivered, but it should be structured so that customers clearly perceive the added value. For instance, you should probably add advanced alerts to an "Enterprise" plan, and possibly limit graph usage for "Starter" plans, etc.

LogDNA is a must have for any tech company

5.0 6 years ago

Comments: LogDNA has been helping us managing logs since early days (when our company was just 5 people). It helps us pro-actively identify bugs/crashes before our customers even had a chance to log support ticket.

Pros:

- LogDNA is very easy to integrate - takes 5min to setup - LogDNA saves disk space - you dont need to store logs in your server anymore - LogDNA views makes it easy to organize logs based on environment, service, filter, etc - LogDNA alerts enable us to pro-actively identify bugs/crashes before our customers even had a chance to log support ticket - LogDNA makes it easier to expose logs to everyone in the team without having to give them access to the production servers

Cons:

There is nothing i like least about this product. Maybe the fact that it gets more expensive as your system and users grows, but thats fair and expected

Easy log management for Kubernetes

5.0 5 years ago

Pros:

- Very fast search over terabytes of data - Easy to integrate with Slack and other tools - Easy to get up and running overall, especially on Kubernetes. Only two lines of code to implement and start seeing it on the LogDNA dashboard - Lets you control what is being stored, and filtering on ingest means you don’t get charged for filtered data, even if you’re still sending it in for tailing. Pretty fair way of doing pricing. - The overall developer experience is good, and quite intuitive to build graphs and dashboards.

Cons:

- Takes a while to dig in and figure out all of the features - Alerting is nice, but could use more customization

Great logging

4.0 5 years ago

Pros:

Really easy to send logs from our servers to LogDNA. We run our workloads on AWS and use the CloudWatch to LogDNA lambda to ship logs to LogDNA... Works like a charm. Love that I can aggregate all my logs from multiple AWS services (a large fleet of EC2 instances and thousands of Lambdas) in to a single log stream. Also really love how I can set alarms for specific strings in the Logs... I get notifications when certain strings appear in the logs which allows me to react to specific events much faster than normal.

Cons:

Searching logs can be cumbersome. It's not simple booleans, which can make things a bit challenging with complex queries.

Great software, helps to keep an eye on business, simple, beautiful interface, fits all needs

5.0 7 years ago

Comments: "One Ring to rule them all" - helps with monitoring cloud environment with many nodes - alerts helps fix a problems.

Pros:

Simple interface, great user experience. Feature-rich: it fits all my needs regarding log monitoring. Multiple integrations support many OS, using dedicated agent makes integration easy. Dynamic development brings new features. Reasonable price.

Cons:

Sometimes there are lags in log processing also I've spotted some missing logs (migrate from syslog to agent integration doesn't fix a problem). Linux agent consume to much memory - it's an issue on cloud VMs with small amount of memory, where overhead on monitoring/logs should be as small as possible. Graphs looks pretty - but should have more interaction with logs filter - eg. filter could map on graph - changing filter conditions change graph conditions as well.

Cons:

Dashboards and metrics based on logs is rather basic. Could use more features and dashboard/charting functionality.

LogDNA is a grat simple product

5.0 6 years ago

Comments: We're trying to ensure that we can watch logs across multiple clusters and multiple machines. This allows any of our developers to watch for errors from a single interface, rather than having so SSH into each machine. We're also not at the scale to run a system like this ourselves, so it's easier to use an existing product, like LogDNA.

Pros:

I love the simplicity of LogDNA. It works well for our small environment and seems to have the ability to scale up. The pricing structure makes sense and suits our needs. It's also super easy to install and set up on our servers. I've managed to add it to the provisioning system that we use.

Cons:

Nothing, at the moment it suits our needs perfectly.

Finally found the solution for tracking our logs!

5.0 7 years ago

Pros:

LogDNA has been a pleasure to use and provides almost everything we need. It was easy to deploy the agent using our existing Ansible scripts and their searching and filtering is very intuitive. Our engineering team makes regular use to find and fix bugs and to understand usage.

Cons:

Would be great to have a feature that shows a list of log entries by frequency and start / end date - hopefully the team will provide in a future release!

Easy Logging

4.0 6 years ago

Comments: Being able to see key activity on the site has really helped with support - as we can identify the actions a user has taken and any errors for bug fixes. Sure, you get this with any logging software, but LogDNA had easy set up, a good free plan, and just seemed really clear compared to the others we tried. I am really happy customer and plan to use LogDNA when I launch more online services.

Pros:

I love how easy LogDNA was to set up on my NodeJS server, and the web-based display of my logs. It makes tracking user actions and errors really simple, and I have been able to quickly identify problems and fix bugs.

Cons:

For a logging service, this ticked all the boxes for me. When there has been an issue (I was getting duplicate logs) - support quickly fixed it.

LogDNA has been by far the best logging and log-shipping tool I've used.

5.0 7 years ago

Pros:

Ease of use, many features, excellent and fast searching functionality, beautiful and easy-to-read UI.

The new charting and graphing tool is great, but it doesn't do quite as much as I would like. Additionally, I wish I could search really old logs.
