Monitor PRI status

Hello all,

 

 I have urgent requirement to monitor the PRI status in terms of and calls connectivity. I could test the call connectivity via

 snmpwalk -v -c Public hostname but I get many  ifIndex,MIB and OID. how could i monitor the status? is there any nagios check?

Is it possible through RTMT tool?

Re: Monitor PRI status

This OID should give you bearer channel status

Re: Monitor PRI status

Hi,

 

These are the OIDs per channel.  Query any of them and the status will be zero or one depending if the channel is active or busy

Re: Monitor PRI status

Hi , 

 

do you have any SNMP system to monitor it, if yes, you could use the OID 1.3.6.1.2.1.10.20.1.2.1.1.2 as mentioned by Mohammed. 

I use Solarwind toolset (SNMP RealTime graph) to perform the real-time monitoring of the PRI status for one of my customers and I configured ODI 1.3.6.1.4.1.9.10.19.1.1.4 and it gives me current active calls(Ds0 channels), the average number of calls and max calls.

 

using RTMT,  you can use call processing activity monitoring where it gives you calls attempted, completed calls, and calls in progress of MGCP and H323 gateways.  I configured here, unfortunately, it is not giving me what I need. you can give a try

Re: Monitor PRI status

Hi yes i have an system to monitor via snmp, but how could i check the status of PRI ?  I get below information using snmpwalk command. is it possible to monitor PRI status with nagios?

SNMPv2SMI::transmission.20.1.2.1.1.2.41 = INTEGER: 1
SNMPv2-SMI::transmission.2.1.2.1.1.2.42 = INTEGER: 1
SNMPv2-SMI::transmission.2.1.2.1.1.2.43 = INTEGER: 1
SNMPv2-SMI::transmission.2.1.2.1.1.2.44 = INTEGER: 1
SNMPv2-SMI::transmission.2.1.2.1.1.2.45 = INTEGER: 1
SNMPv2-SMI::transmission.2.1.2.1.1.2.46 = INTEGER: 1
SNMPv2-SMI::transmission.2.1.2.1.1.2.47 = INTEGER: 1
SNMPv2-SMI::transmission.2.1.2.1.1.2.48 = INTEGER: 1

Re: Monitor PRI status

As per my understanding,

you should have the base MIB in your system to read the values of OID from your SNMP application. The output should be present after the integer value .

 

the following document may help you further on this. Monitor E1/T1 Channel Usage via SNMP

And related to Nagios, yes you can use this application to monitor it (as per the Nagios support thread). ensure that you have the necessary MIB available in their repository, for the 1.3.6.1.2.1.10.20.1.2.1.1.2  - it is  ISDN-MIB and 1.3.6.1.4.1.9.10.19.1.1.4 it is CISCO-POP-MGMT-MIB.

Re: Monitor PRI status

 So we should resgister these MIB first

Re: Monitor PRI status

Hi,
Depends on your SNMP application, these MIBs may come inbuilt. if you want to download it, then you can get Cisco MIB from https://snmp.cloudapps.cisco.com/Support/SNMP/do/BrowseMIB.do?local=en&mibName=CISCO-POP-MGMT-MIB and isdn MIB from the link - https://www.activexperts.com/admin/mib/rfc/isdn-mib/

you should have the proper SNMP string and host configured in VG to get the access from your SNMP applications.

 

see if you can get the gateway configuration. for example, I have configured as below in my gateway initially;

For example;
snmp-server community j63*gwe14 RO 1320  # the bolded item is the snmp string 
snmp-server host <ipaddress> j63*gwe14 # where the IP address is snmp application server.

 

hope it helps you

Regards,

Shalid

Re: Monitor PRI status

Hi SNMp is already configured,and I am able to access the snmp from the other server. I get the channels but it can show as up when the call is running, it doesnot show if the pri is running. to check PRI signalling channel 0/1/0 is needed. How could i do that

Re: Monitor PRI status

 Hi,

cpmDS1ActiveDS0s i would like to monitor the MIB but unfortunatly i am getting an error . could you please help


snmpwalk -v2c -c Netsee host.com 1.3.6.1.4.1.9.10.19.1.1.4
CISCO-POP-MGMT-MIB::cpmActiveDS0s = No Such Object available on this agent at this OID

CISCO-POP-MGMT-MIB::cpmDS1ActiveDS0s = No Such Object available on this agent at this OID

Re: Monitor PRI status

one quick question - is it MGCP or H323 gateway  and also the gateway mode please? 

Regards,

Shalid

Re: Monitor PRI status

Its not MGCP oder H323. The communication runs over SIP

Re: Monitor PRI status

!!!!!

The previously mentioned OID and Mib is work for only PRI on H323 gateways. If you have a CUBE in place and the connectivity is SIP then you should look for other MIB's. 

 

You can try CISCO-VOICE-DIAL-CONTROL-MIB or  DIAL-CONTROL-MIB MIB for your purpose. 

Try the OID - 1.3.6.1.4.1.9.9.63.1.3.3 - this should work for both SIP and PRI and the MIB and you need is CISCO-VOICE-DIAL-CONTROL-MIB.

 

Also could you please let us know what is your connectivity, is it PRI or SIP channel. 

Regards,

Shalid
