Bandwidth Performance Graphs Issue

[[email protected]]

Hello,

We are from "dpiX" our Customer number: 39619. Installed Nagios XI version 5.2.9 with Standard License, We added the device successfully with services like Ping with graph, Port Status and Bandwidth Graph.

In this we are not able get Bandwidth Graph for any devices, For reference find the attachment of Bandwidth.jpg and Bandwidth Performance Graph.jpg.

Common Service setting we applied for all the interfaces are followed below

1. Check Command: Check_xi_service_mrtgtraf

2. Command View: $USER1$/check_rrdtraf -f /var/lib/mrtg/$ARG1$ -w $ARG2$ -c $ARG3$ -l $ARG4$

3. $ARG1$: 10.10.10.2_1023.rrd

4. $ARG2$: 500.00,500.00

5. $ARG3$: 800.00,800.00

6. $ARG4$: M

Please find the attachment of Bandwidth service settings.jpg for reference.

Kindly do the needful, Let us know if you require any more details.


Thanks,
Kondal Reddy

Increased Forks value 4 to 8 and restart crond service, No change.

Edited the SNMP configuration Incorrect steps to one of the switch added in Nagios XI, no change.

Tried the two links before reaching you, did not got any change in graph.

Are you seeing anything that may be related in your /usr/local/nagios/var/npcd.log, /usr/local/nagios/var/perfdata.log, or in /usr/local/nagiosxi/var/perfdataproc.log?

Thank you

[lmiltchev]

It seems like you commented out the "default" mrtg cron command, and added a custom script...

[root@cs1-prd-cmn-nag01 ~]# cat /etc/cron.d/mrtg
*/5 * * * * root /root/mrtg.sh
#*/5 * * * * root LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg --lock-file /var/lock/mrtg/mrtg_l --confcache-file /var/lib/mrtg/mrtg.ok

I am not sure that is going to be a supported Nagios XI instance. Can you show us the script?

Code: Select all

/root/mrtg.sh

We are running MRTG on the same machine where Nagios XI is installed.

The mrtg.sh script file I created for MRTG.

Output:

I did not created any thing like this for Nagios XI, Should I UN-comment that line.

Please give the examples to add lines for devices in /etc/cron.d/mrtg, If required.


Thanks

[tgriep]

Since the cron tab entry calls a script and is may not have the config files for that device in it, let's put it back so it will not cause problems now and in the future.

Edit this file

Code: Select all

/etc/cron.d/mrtg

Change this from

Code: Select all

*/5 * * * * root /root/mrtg.sh
#*/5 * * * * root LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg --lock-file /var/lock/mrtg/mrtg_l --confcache-file /var/lib/mrtg/mrtg.ok

to

Code: Select all

#*/5 * * * * root /root/mrtg.sh
*/5 * * * * root LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg --lock-file /var/lock/mrtg/mrtg_l --confcache-file /var/lib/mrtg/mrtg.ok

Also, make sure the MRTG application is upgraded by following this article.
https://support.nagios.com/kb/article.php?id=511

Wait for about 15 minutes for the bandwidth information to update, if they do not, run the following and post the /tmp/mrtg.txt file.

Code: Select all

LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg -debug=cfg,base &> /tmp/mrtg.txt

[tgriep]

I forgot one step, You may want to copy the device cfg files from the /etc/mrtg folder to the /etc/mrtg/conf.d folder if they are still needed so the default settings will pick them up.

Yes I got the output by UN-commenting

/etc/cron.d/mrtg

*/5 * * * * root LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg --lock-file /var/lock/mrtg/mrtg_l --confcache-file /var/lib/mrtg/mrtg.ok



Actually I added all the nodes with SNMPv3 except one, Which is added with SNMPv2.

Please find the attached screen shots of the node which added with v2 and getting output. (Bandwidth & Bandwidth 1)


I just followed your article https://support.nagios.com/kb/article.php?id=29

steps:

SNMP Configuration Incorrect

Older verions of the Switch Wizard called mrtg with arguments for SNMPv2c, which MRTG does not use. Here is an example of an incorrect setting from a config file in /etc/mrtg/conf.d/:

Target[www.hostaddress.com]: 1:[email protected]:::::2c

Notice that after the multitude of colons, there is a 2c, this represents the SNMP version MRTG will use to poll the device. If this is instead 2c, change it to 2 and save the file. This will need to be done to every metric that is affected by being created with 2c. Entries should look like:

Target[www.hostaddress.com]: 1:[email protected]:::::2


Testing on one node which is added with v3 and made changes as above, I got the graph and it went back IN/OUT to zero 0 after few minutes.Observed about an hour, still no output.

Find attachments of testing screen shots as Test1.

Please help me to get it continuously.


Thanks
