Nagios Support Forum

Good morning,

There have been a number of changes to an edge router since it was added to Nagios via the 'Network Switch / Router' Configuration Wizard. I tried removing the router, and then re-adding it again using the 'Network Switch / Router' Configuration Wizard so that it perform another snmpwalk, but it seems to retain out dated/inaccurate data about the interface (services) on the router.

Here is example of what I am seeing:

GigE3/18 - Veeder Root FCU Status CRITICAL: Interface GigabitEthernet3/10 (index 18) is down.
GigE4/18 - Sting Schools -AHS Status CRITICAL: Interface GigabitEthernet4/10 (index 42) is down.
GigE7/1 - Lab-RDU-4.0 Status CRITICAL: Interface GigabitEthernet4/21 (index 53) is down.
GigE7/4 - To-Shippenville ONS-1 Status CRITICAL: Interface GigabitEthernet4/24 (index 56) is down.
GigE4/17 - Sting Schools -IU8 Status CRITICAL: Interface GigabitEthernet4/9 (index 41) is down.
GigE7/23 - NetScreen Status CRITICAL: Interface GigabitEthernet7/15 (index 75) is down.
GigE7/33 - NS01.atlanticbb.net -Primary Status CRITICAL: Interface GigabitEthernet7/25 (index 85) is down.
GigE7/34 - Motive-1_Server Status CRITICAL: Interface GigabitEthernet7/26 (index 86) is down.
GigE7/35 - T0-Bradford-ONS-Slot-4 Port-5 1 Status CRITICAL: Interface GigabitEthernet7/27 (index 87) is down.
GigE8/7 - fw-1-outside Status CRITICAL: Interface GigabitEthernet7/47 (index 107) is down.
GigE8/35 - To-SBC-01-02 Management Status CRITICAL: Interface GigabitEthernet8/27 (index 135) is down.

The information about the interface in the left column, does not match the right column and it is the same interface. Plus the information is out dated/inaccurate. The pull the data up vi the "Service Details" option under the "Details" menu for our router. I hope this makes sense. It is as if the NAgios database remembers the old data even after the router is deleted and re-added via the Configuration Wizard???

What is the recommended way to update the configuration of a switch/router once it has bee defined in Nagios.

Thank you,

Mark,

Nagios XI keeps all of the config files in the

/usr/local/nagiosxi/tmp/ as mrtgscan-<IPADDRESS OF DEVICE>

Can you check in the directory and delete the corresponding mrtgscan file and then try re-running the wizard?

Do I have to delete all of the services (about 180) definition and then host definition in Nagios Core Configuration Manager before I delete the /usr/local/nagiosxi/tmp/ as mrtgscan-<IPADDRESS OF DEVICE> files? I see three different files with different time stamps???

[root@trends tmp]# ls -ltr *er-1.aoo*
-rw-r--r-- 1 nagios nagios 0 Feb 14 11:28 mrtgscan-er-1.aoo.pa.atlanticbb.net_l
-rw-r--r-- 1 nagios nagios 334260 Jul 27 05:45 mrtgscan-er-1.aoo.pa.atlanticbb.net
-rw-r--r-- 1 apache nagios 0 Aug 11 15:25 mrtgscan-er-1.aoo.pa.atlanticbb.net.done

I deleted and added the device yesterday...

Thank you

Nope, those files in the tmp directory are ONLY for the wizards during setup, they aren't referenced after that.
