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

In addition to the previous message, please send the output of these commands:

If you run a packet capture, do you see packets coming in from that host?

yum install tcpdump
tcpdump -nni any host X.X.X.X and port XXXX

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
