Auxiliary lines can now be drawn on graph widgets in custom dashboards
The custom dashboard's graph widget now supports drawing auxiliary lines at any specified value.
We hope you will find this useful for setting yardstick values on your graphs, such as past results or projections.
The label you enter when configuring an auxiliary line is displayed when you mouseover the flag icon to the right of the line. This can be useful to add notes or comments!
mackerel-sql-metric-collector has been made available under mackerelio-labs.
As mentioned in the recently published article "Introduction to service operation through SLI/SLO using Mackerel", we have released mackerel-sql-metric-collector is now available! This tool allows users to post the results of queries made to Amazon Athena and supported RDBMSes as metrics.
As shown in the introductory article, we believe this tool will strengthen your monitoring on Mackerel by, for example, helping with SLI/SLO monitoring by aggregating latency data from Athena ALB logs. We hope you'll find it useful!
The Mackerel team also releases software resulting from new initiatives on the mackerelio-labs GitHub Organization.
More new software is planned for release in future, so make sure to keep an eye out!
