Hello,

I install Nagios Log Server manually on CentOS.

Everything was going great, I left for the weekend only to find it not working.
It looks like the disk is full, and I was having trouble with it automatically deleting indexes (despite it being set to delete indexes older the 2 days in the maintenance and backup)

My first question: is there anyway to delete indexes manually from the command line so I can get the server back up?

Second question: what could be causing the issue where the server does not delete old indexes?

Thanks for any help you can provide.

You should be able to delete them through the UI, however you may need to free a little space to be able to get it the UI up and running.

Here's what I would suggest to free up some space

Code: Select all

service logstash stop
service elasticsearch stop
rm -rf /var/log/elasticsearch/*/*.log*
cat /dev/null > /var/log/logstash/logstash.log
service elasticsearch start

Wait a minute for it to load, then delete indexes manually through Admin -> Manage Indexes

Then

Code: Select all

service logstash start

Finally, lets verify what the settings are on the backup and maintenance page, can you post a screenshot?

That worked out great, thank you.

Here's the screen shot of the backup and maintenance page settings.

It looks like you have not setup a Backup Repository, below is the link on how to create one.
If you choose a drive with more free space, you shouldn't have any more problems.

Thanks again, we'll see what happens over the next few days.
