Mackerel agent is now officially supported on Amazon Linux 2023.
Mackerel agent is now officially supported on Amazon Linux 2023, which was became generally available yesterday.
It can be installed with the one-liners or rpm commands listed on this help page.
The commands are also listed on the page for registering new host, so please use them.
We added new metric targets that can be retrieved from Aurora Serverless v2 instances through AWS integration.
As previously announced, we have added new metric targets that can be retrieved through linking with Aurora Serverless v2 instances in AWS integration.
For details on the changes to the specifications and the impact of these changes, etc., please read this entry.
We changed some metric targets that can be retrieved from Azure SQL databases with Azure integration.
The In-Memory OLTP Storage metric, which is only available for Azure SQL Database SKUs of Premium level or Business Critical level, was previously posted with a value of zero even for SKUs that are unable to access these metrics, but we have changed it so that it is no longer posted.
| Affected Metric | Metric Name in Mackerel |
|---|---|
In-Memory OLTP Storage percentage(xtp_storage_percent) |
azure.sql_database.xtp_storage.percent |
We fixed an issue with mackerel-plugin-php-apc which caused retrieving metrics from APCu in PHP 7 or later to fail.
This fix will be included from the version below forward.
- mackerel-agent-plugins v0.78.0
