2014R1.0RC1 Initial reaction and question(s)

[b2m]

Actually, I believe there may be a bug in the command definition

Can you run the following?

Code: Select all

./check_ifoperstatnag 10124 -v 3 -u manager -A xxx -X xxx -l authPriv 192.168.120.126

either way, we will be testing this internally and get it sorted BEFORE the full 2014 Release

No, it's the same error then.

Code: Select all

[root@localhost libexec]# ./check_ifoperstatnag 10124 -v 3 -u manager -A df3Uvo0QfaA1bP3n -X 1qv6hJ3C9Q1PvzR8 -l authPriv 192.168.120.126

./check_ifoperstatnag: line 18: [: -eq: unary operator expected
./check_ifoperstatnag: line 21: [: -eq: unary operator expected

The script looks to me like it could only handle SNMPv1/v2c, buzzword "community string". Would you also look into the path thing with cfg-maker? I'm sure many customers will need reliable SNMPv3 for the wizard .

Thanks.

I just looked at your command again and it is missing several of the required args like

Code: Select all

-a md5 -x DES

However, the developer jus took a look at the wizard and determined there were a couple bugs in it and here is the fix (until the next release)

Install the attached wizard via Admin -> Manage Wizards

switch.zip

Also, make /etc/mrtg/mrtg.cfg contain just the following:

Code: Select all

# Minimal mrtg.cfg
#--------------------

HtmlDir: /var/www/mrtg
ImageDir: /var/www/mrtg
LogFormat: rrdtool
LogDir: /var/lib/mrtg
ThreshDir: /var/lib/mrtg
WorkDir: /var/lib/mrtg

Include: conf.d/*.cfg

Finally, re-run the wizard for your host

Hi,

I still got no success with your new version.

The wizard now generates:

Code: Select all

check_xi_service_ifoperstatusnag!10122!-v3 -u manager -A xxx -X xxx -a SHA -l authPriv

This results in the following script execution:

Code: Select all

[root@localhost libexec]# ./check_ifoperstatnag 10122 -v3 -u manager -A df3Uvo0QfaA1bP3n -X 1qv6hJ3C9Q1PvzR8 -a SHA -l authPriv 192.168.120.253
Timeout: No Response from 192.168.120.253
./check_ifoperstatnag: line 18: [: -eq: unary operator expected
./check_ifoperstatnag: line 21: [: -eq: unary operator expected
WARNING - No info is being retrieved

Correct would be something like:

Code: Select all

[root@localhost libexec]# ./check_ifoperstatnag -v3 -a SHA -A df3Uvo0QfaA1bP3n -l authPriv -u manager -x AES -X 1qv6hJ3C9Q1PvzR8 192.168.120.253 IF-MIB::ifOperStatus.10122
OK - Interface -v3 is up.

So add the encryption method (-x) and everything is fine . Default seems to be DES and it doesn't seem to distinguish between AES128, AES192 and whatever.

You should also add the if-name as it was in the old wizard so that it shows something like:

Code: Select all

OK - Interface Gig0/24 is up.

[abrist]

check_xi_service_ifoperstatusnag!10122!-v3 -u manager -A xxx -X xxx -a SHA -l authPriv

What is "10122" ? What wizard form generated that?

[b2m]

check_xi_service_ifoperstatusnag!10122!-v3 -u manager -A xxx -X xxx -a SHA -l authPriv

What is "10122" ? What wizard form generated that?

The SNMP interface-id. It is generated by the switch wizard.

[sreinhardt]

OK, I see what you are saying with the commands that are defined. Going to check some things and will be back with more info or a fix from us.

Hi, are things working fine?

Is there any need for a basic perl plugin that can do snmp polling of switch / router interfaces and write it to xml? I'm currently working on such a thing for using it here. I could provide it for download somewhere when I'm done.

[tmcdonald]

MRTG should take care of that already, but having it in a single plugin might be useful. Feel free to upload it to exchange.nagios.com if you'd like.

[b2m]

And did you do something in the final version regarding the wizard?

[lmiltchev]

I don't think so, at least I don't see this listed under "WIZARDS":
