Grafana Loki vs. Sentry

Grafana Loki can compile data logs for easy exploration of a service and enable quick troubleshooting and error tracing for engineers who may not have deeper access. However, Loki is dependent on the service logging complexity, which, depending on the logger, may not be robust enough and limit the value offered.

Great for standard web application performance monitoring, analytics and error reporting. Shows line level code errors, gives insight into performance issues (plugins, API issues, etc.). Automation and scheduled scanning in production gives client visibility into 'after deployment' value. Also lets a relatively small number of developers keep tabs on a handful of different site/applications without needing a bunch of tools. The UI is pretty complicated and can be overwhelming for new users. Documentation could be better for the learning curve,

Incentivized

• Access to many open-source dashboards, access to add many data-sources to gather and visualize data from.
• Grafana Loki does well gathering of logs from various data-sources, we can also filter the logs based on our needs.
• One stop solution for all the logs and monitoring.

Incentivized

• Great web interface. Lots of data available in a really clean format, with filtering options and more.
• Per-user exception tracking. User is complaining about something being broken? Look up their account ID in Sentry and you can see if they've run into any exceptions (with device information included, of course).
• Source map uploading. Took a little while to figure this out but now we have our deploy script upload sourcemaps to Sentry on each deployment, meaning we get to see stack traces that aren't obfuscated!
• Very generous free tier – 10,000 events per month. We're nowhere near that yet.

Incentivized

• Learning curve is very steep
• Longer term log insight is a challenge
• Very easy on AWS, integration with other systems can be more of a challenge

Incentivized

• Alert Configuration. Would be really helpful to have multiple logical groupings within the "If" section of a single configurable alert.
• Alert Copying. Being able to copy an alert from one project to another would be super beneficial.
• Alert Tags. Better UI around how we select which tags are getting sent with each alert instead of a tiny text box.

Grafana Loki makes accessing and viewing service logs easy for engineers who may not be familiar with going into service. However, useability can be limited if engineers are unaware of what the queries should look like or where in the service to direct Loki to look for logging.

First and foremost if Grafana Loki is based on CNCF open source projects so organizations can get freedom to choice to configure it at your own other main thing is Grafana Loki is totally free of cost and we can deploy it on our infrastructure. On compared with other managed services like Datadog, New Relic it is very expensive and we also don't have much control on the tools we use.

Incentivized

We used Rollbar but didn't like the configuration its not easy. And also doesn't support wide features like Sentry although its a cheaper option but doesn't have the dash-boarding like Sentry and its was not easy to integrate webhooks for different purposes. Somehow many people in company where not able to understand Rollbar dashboard who were very much used to Sentry.

Incentivized

• Company wide (realtime) insights in complex aws setup is great
• Dashboarding options are easily set up

Incentivized

• It helped stabilize our system in the beginning
• We had to take it down later due to internal reasons and majorly because of cost-cutting process
• If someone has a unstable system and have no way to figure out what to do, can use sentry at least temporarily along with some other APM to fix their system faster
