Brewing in Beats: Monitor PHP-FPM and Ceph

Welcome to the weekly Brewing in Beats ! With this weekly series, we are keeping you up to date with all the changes in Beats, including the latest commits, releases and other learning resources.

Monitor PHP-FPM

Thanks to our colleague Thiago Souza, PHP-FPM module is added in Metricbeat to collect server status metrics from PHP-FPM. It gives you metrics like the current number of queued connections that have initiated, but not yet accepted, or the number of active servers that are currently processing a page.

Monitor your Ceph storage platform

Thanks to Amanda H. L. de Andrade, Ceph support is added in Metricbeat as a community contributionCeph is a distributed object, block, and file storage platform. Metricbeat collects periodically metrics from Ceph by submitting HTTP GET requests to ceph-rest-api.

Custom HTTP headers for the Elasticsearch output

With this change, you can configure to add custom HTTP headers in the request to Elasticsearch. An interested use-case might be a custom authentication to Elasticsearch.

The HTTP headers should be configured under the Elasticsearch output:

  X-My-Header: Contents of the header

And we can also configure the HTTP headers from the CLI:

metricbeat -E "output.elasticsearch.headers.X-test=Test value"
