Insufficient disk space

ele30 — Fri, 18 Oct 2024 06:52:24 GMT

We use dynatrace managed and are receiving these warnings:

Insufficient disk space on /opt/dynatrace-managed/cassandra (/dev/mapper/VG--dynatrace-LV--cass) on SERVER at location 'location' (id=6).

I've read the documentation but seems like a delicated task, anyone have some advice? Thanks.

Hello @ele30

Regarding the received warning events, it's an alert to increase the allocated storage resources for the Dynatrace cluster nodes.
It's recommended to keep all cluster nodes equally sized and assign sufficient storage resources as it's mostly consumed for the RUM , Transactions , and Logs.
It's better to have at least 1 TB on each cluster nodes and extend it periodically as per the monitoring requirements.

KR,

Peter.

Hello @ele30

Simply you will take a screenshots from the severe events and advice the infrastructure team to increase the storage resources on the 3 cluster nodes equally.

Hi @ele30

You can find the managed HW requirements

https://docs.dynatrace.com/managed/setup-and-configuration/managed-cluster/installation/dynatrace-managed-hardware-and-system-requirements
It depends on the actual nodes sizing as per the current deployed setup.
The notification shows that Cassandra directory has no sufficient storage.

KR,

Peter
