Hi Team,

We are getting "No data available" on the bandwidth graph in the Nagios network analyzer.

It was showing 2 days before but suddenly it is not showing. Able to see flow file is updating

Attached the screenshot and txt file with permission of rrd file.

Thanks

Hi @mejokj,

Let us know if that resolves the issue or not. If not please post a tail output of the Apache and the database logs.

Code: Select all

tail -n 100 /var/log/httpd/*error_log
tail -n 100 /var/log/mariadb/mariadb.log
If these commands do not work, let us know what operating system your are own. The location may be different.

Thanks,
Ben
