#1599 Alert Threshold value 0 is not allowed Issue created by DamZiobro Bug description When I create new alert in SigNoz UI and try to set 'Alert Threshold == 0' I get the following error. As a workaround I can use very low fraction value ex. 0.0000001, but it is not very intuitive. Alert Threshold 0 should be valid. Expected behavior Setting of Alert Threshold 0 should be allowed in Alert manager. How to reproduce 1. Install SigNoz using default setting of standalone Docker. 2. Try to create some Alert in SigNoz UI and set 'Alert Threshold' value to 0. 3. You should see the error as reported above. SigNoz/signoz

#2790 feat: add zap otel logger support Pull request opened by makeavish SigNoz/signoz GitHub Actions: playwright ✅ 8 other checks have passed 8/9 successful checks

#2795 Clickhouse otel collector stopped processing telemetry data Issue created by strainovic Bug description After using SigNoz for some time, we've noticed that telemetry data have been delayed and eventually stopped processing at all. In the clickhouse hotel collector log, we've found something like this:

Unexpected transport closing: too many pings from client

We've noticed this issue on Java-based services:

[otel.javaagent 2023-05-30 06:20:13:532 +0000] [OkHttp <http://otlp.dev:4317/...>] ERROR io.opentelemetry.exporter.internal.okhttp.OkHttpExporter - Failed to export metrics. The request could not be executed. Full error message: Connection reset

#2796 fix: mutex lock to avoid concurrent map writes Pull request opened by makeavish fixes: #2596 SigNoz/signoz GitHub Actions: playwright GitHub Actions: Codeball ✅ 7 other checks have passed 7/9 successful checks

#2797 Don't call query range APIs when user updates layout on dashboard Issue created by makeavish Currently whenever user updates layout on dashboard, then query range APIs are called for all dashboard panels. This is unnecessary. SigNoz/signoz

#2798 Saving a dashboard is not intuitive Issue created by makeavish We should either enable autosave on dashboard or introduce a popup when user moves away from a unsaved state(unsaved dashboard or panel). Loom video explaining the issue: https://www.loom.com/share/36a93febda004e41b8d6aea8eae6a113 SigNoz/signoz

#2799 Sync issues on dashboard when multiple users are editing dashboard Issue created by makeavish When user A makes changes to the layout of the dashboard and user B adds a new panel then the last user who saved the dashboard will be in the final state thus undoing the other user's changes. SigNoz/signoz

#2782 feat: add querier interface and initial implementation Pull request opened by srikanthccv Part of #1988 This introduces a querier interface which will be responsible for running the queries for query range requests with optional caching. The current implementation doesn't do any caching for traces and logs query range requests and doesn't support ClickHouse query since it can be very dynamic in nature. Otherwise, the following is the flow. • Create a cache key for the builder query • See if there is cached data from the previous run • Find the missing time range by comparing the current start, and end with the cached start and end • Query data for the missing time ranges • Prepare the new merged series from the cache data and query data • Store this for the potential next There are some configurable options, 1. Flux interval - querying and caching the more recent data could give incorrect results since some data might not arrive yet. This setting prevents the caching of very recent results that might still be in flux. Default 5 minutes. If you believe this is low, we can bump it up. 2. NoCache - Option for the client to disable the caching entirely. SigNoz/signoz GitHub Actions: playwright ✅ 8 other checks have passed 8/9 successful checks

#2773 feat: add measurement value formatter Pull request opened by srikanthccv Part of #2548 This adds support for formatting a value from the measurement unit. This is the second part of adding support for unit support. Say the user is reporting the disk size in bytes. The selected Y-Axis format makes it human-readable when they view data in UI. This formatting is currently done on the UI side only; this is still a bytes number for the backend. Going forward with this formatter will make alert description contains a user-friendly value.

dataFormatter.Format(82854982, "bytes") = 83MB

Why do we need both a converter and a formatter? The formatter simply humanizes the value. This is usually the value from the ClickHouse query output. The converter comes into the picture when the threshold is involved. The user sees the chart with 300 MB (Y-Axis) but wants to set the threshold to 2 GB, so we need to convert the 2 GB into MB for comparison. These two will be seen in practice in follow up draft PR.
