Overview

This article addresses the issue of ASGARD Analysis Cockpit malfunctioning when your disk is full or nearly full. To restore its operation, free up disk space.

Prerequisites

The Analysis Cockpit does not work properly. If this is not the case, please modify the Data Retention Policy to free disk space:

Save the files to another system if you want to keep the information. ASGARD does not require the following files and they can be safely removed:

• /var/lib/asgard-analysis-cockpit/log/*.gz

• /var/lib/asgard-analysis-cockpit/events/*.ok

Expected result

The Cockpit functions properly again. Further optimizations are possible via:

• Optimizing Data Retention (https://analysis-cockpit-manual.nextron-systems.com/en/latest/maintenance/retention.html )

• Extending ASGARD's Disk Space

• Managing Disk Space in Analysis Cockpit: Safe and Unneeded File Deletion Options

Steps to reproduce

Step 1: Delete to required files

nextron@cockpit:~$ sudo -s
[sudo] password for nextron:
root@cockpit:~# find /var/lib/asgard-analysis-cockpit/events -name "*.ok" -print0 | xargs -0 -I'{}' rm '{}'

Step 2: Restart Elasticsearch

If Elasticsearch does not automatically work again after cleaning up some disk space, restart it under Settings > System > Services or with sudo systemctl restart elasticsearch.service.
