How to avoid daily creation of .monitoring system indices (v7.14)

Hi All,

I see daily system indices (.monitoring...) getting created. How can we avoid creation of these indices daily and instead create them on monthly basis.

I am aware of ILM and using it for application indices to rollover based on some condition.

for beats indices i have configured like below in logstash.conf, so they are getting created monthly.

/etc/logstash/conf.d/logstash.conf

how can we do these for .monitoring indices?

Thanks,

I just noticed at any time there are only 7 such indices. So the older one are getting automatically deleted.

Yes. That's how it works by default. 7 days of monitoring data. So there's no need to change the default naming IMO.

In case you want to change something, you should read from How monitoring works | Elasticsearch Guide [7.15] | Elastic

If something is unclear, please tell which method you are using to monitor your cluster, from the legacy to the newest one.
