Performance graph not working anymore

Hi,
Yesterday we did reconfigure some networks devices (Routers and Switches) to work with SNMP v3 rather than SNMP v2c. After that all hosts (servers, network devices, etc.) monitored within Nagios XI stops showing performance graphs with "no data to display".
- Nagios XI 5.5.7
- CentOS 6.8
- 128 monitored hosts
- 1956 monitored services
- Attached our system profile
Let me know if you need any more information for troubleshooting. Thanks in advance!
Regards,
Amine

Edit the following file
/etc/cron.d/mrtg
Change this line from
Code: Select all
*/5 * * * * root LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg --lock-file /var/lib/mrtg/mrtg.lock --confcache-file /var/lib/mrtg/mrtg.ok --user=nagios --group=nagios
to
Code: Select all
*/5 * * * * root LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg --lock-file /var/lib/mrtg/mrtg.lock --confcache-file /var/lib/mrtg/mrtg.ok
Save the file and restart cron by running
service crond restart
Another thing, you will have to re-run the Network Switch / Router wizard against each device so it can add the SNMPv3 authentication data to the MRTG config files.
First, upgrade the Network Switch / Router wizard in XI by logging in to the XI GUI and going to the Admin > Manage Config Wizards menu.
Click the Check for Updates button and update the Network Switch / Router wizard.
After the changes, wait for 15 minutes and see if the Bandwidth Graphs and the other graphs start to populate with data,

Hi,
i follow the steps and in the same time update Nagios XI to 5.5.10 version but nothing change and no data is displayed on the graph. Also the GUI is taking too much time to respond when navigating through the web interface
