Can you enable snmptrad debug and check with argument and value you receive?

I receive this output from trap:

1 07 E8 05 15 10 0B 19 00 S-Edition Primary Select 11.1.3.1.0 build 34 1

1 07 E8 05 15 10 0D 37 00 S-Edition Primary Select 11.1.3.1.0 build 34 4

The last digit is the string that I need to wortk with (1 or 4).

he re is my configuration on advanced matching rules and the debug output:

2024-05-22 18:56:49 - ERROR - 5247 - Dont skip trap. Need to solve the error.

#############################################################

I don’t know why the trap don’t take care about regexp that I put.

Here is the full output for trap for each service:

1 07 E8 05 15 12 32 35 00 S-Edition Primary Select 11.1.3.1.0 build 34 1 => service 1

1 07 E8 05 15 10 0D 37 00 S-Edition Primary Select 11.1.3.1.0 build 34 4 => service 4

HI,

According to the documentation and your screenshot:

If “Output message = $5”, $5 can contain 1 or 4.

So for the advanced matching rules you should have:

Hi,

I Tried that but doesn’t work because for both services, the string 1 or 4 is present at the begin of the output (argument $1) for alarm severity:

1 for severity (Cleared) and 4 for severity (Major)

1 07 E8 05 15 12 32 35 00 S-Edition Primary Select 11.1.3.1.0 build 34 1
1 07 E8 05 15 10 0D 37 00 S-Edition Primary Select 11.1.3.1.0 build 34 4

4 07 E8 05 15 12 32 35 00 S-Edition Primary Select 11.1.3.1.0 build 34 1
4 07 E8 05 15 10 0D 37 00 S-Edition Primary Select 11.1.3.1.0 build 34 4

So the reult is send for both services always, and that is wrong.

Example 1: I turn on Voicemail service, see below both services are OK

Example 2: I turn off OneX Portal service: see below both services are Critical:

So you can use /^4.*/, this means that the value must start with 4

In my case, here is the condition:

Voicemail service

• service DOWN: the output of trap is:
• 4 07 E8 05 15 12 32 35 00 S-Edition Primary Select 11.1.3.1.0 build 34 1
• service UP: the output of trap is:
•  1 07 E8 05 15 12 32 35 00 S-Edition Primary Select 11.1.3.1.0 build 34 1

OneX Portal service

• service DOWN: the output of trap is:
• 4 07 E8 05 15 12 32 35 00 S-Edition Primary Select 11.1.3.1.0 build 34 4
• service UP: the output of trap is:
•  1 07 E8 05 15 12 32 35 00 S-Edition Primary Select 11.1.3.1.0 build 34 4

So I will try this regex and give you feedback if it’s work:

1. On trap definition for services when are DOWN

@OUTPUT@                  /^4.*1$/

@OUTPUT@                  /^4.*4$/

2. On trap definition for services when are UP

@OUTPUT@                  /^1.*1$/

@OUTPUT@                  /^1.*4$/

It doesn’t work, something is wrong and I don’t found what is it.

The issue is that centreontrapd switch both services by receiving the trap:

Both services switcyh to OK, but only service “Voicemail service” must switch to OK

Here is my config:

This is “normal”.

You have 2 matching rules on your trap definition and you link this one to your both service.

Si if a matching rule matches, both service will change in the same time.

You can use Centreon DSM or declare 2 SNMP traps definition with each one 1 matching rule.

Are you sure ? It’s normal to link multiple services to a signgle trap definition with many matchging rules.

I have a working example.

This is the way to configure traps when the constructor provide a unique base OID for multiple alarms.

You cannot create both trap definition with the same OID:

Here is my working example:

For me, the issue come from Centreon, maybe a limitation or a bug ?
