Monitoring Connector Assets​

Monitored Objects​

The Monitoring Connector Acme Packet SNMP collects metrics for:

  • Codec
  • Hardware
  • Interfaces
  • Policy servers
  • Realm
  • Security
  • Sip
  • System

Discovery rules​

Rule nameDescription
Net-Acmepacket-SNMP-Interface-NameDiscover network interfaces and monitor bandwidth utilization
Net-Acmepacket-SNMP-Policy-Server-NameDiscover external policy servers and monitor statistics
Net-Acmepacket-SNMP-Realm-NameDiscover realms and monitor utilization
Net-Acmepacket-SNMP-Sip-NameDiscover Sip interfaces and monitor utilization

Collected metrics & status​

Metric nameDescriptionUnit
transcoding.sessions.active.countTotal number of active transcoded sessions
transcoding.resources.usage.countNumber of transcoding resources currently in-use
transcoding.resources.free.countNumber of transcoding resources currently free
transcoding.resources.usage.percentageThe percentage of transcoding resources currently in-use%

Prerequisites​

To control your Acme Packet, the SNMP must be configured.

Setup​

  1. Install the Centreon Plugin on every Poller:
yum install centreon-plugin-Network-Acmepacket-Snmp
  1. On the Centreon Web interface in Configuration > Monitoring Connectors Manager, install the Acme Packet Monitoring Connector

Host configuration​

  • Add a new Host and fill the IP Address/FQDN, SNMP Version and SNMP Community fields according to the device's configuration
  • Apply the Net-Acmepacket-SNMP-Custom Host Template

When using SNMP v3, use the SNMPEXTRAOPTIONS Macro to add specific authentication parameters More information in the Troubleshooting SNMP section.

SNMPEXTRAOPTIONSConfigure your own SNMPv3 credentials combo

How to test the Plugin and what are the main options for?​

Once the plugin installed, log into your Centreon Poller CLI using the centreon-engine user account and test the Plugin by running the following command:

/usr/lib/centreon/plugins/centreon_acmepacket_snmp.pl \
    --plugin=network::acmepacket::snmp::plugin \
    --mode=system-usage \
    --hostname=10.30.2.114 \
    --snmp-version='2c' \
    --snmp-community='acme_ro' \
    --warning-cpu-load='90' \
    --critical-cpu-load='95' \
    --verbose

Expected command output is shown below:

OK: System usage is ok | 'health.score.percentage'=100.00%;;;0;100 'cpu.utilization.percentage'=2.00%;0:90;0:95;0;100 'memory.usage.percentage'=9.00%;;;0;100 'licence.usage.percentage'=0.00%;;;0;100 'sessions.current.count'=0;;;0; 'calls.current.count'=0/s;;;0;
checking system
    health score: 100.00 %
    cpu load: 2.00 %
    memory used: 9.00 %
    license used: 0.00 %
    current sessions: 0
    current calls: 0/s
    replication state: active

The command above monitors Acme Packet (--plugin=network::acmepacket::snmp::plugin --mode=system-usage) identified by the IP address 10.30.2.114 (--hostname=10.30.2.114). As the Plugin is using the SNMP protocol to request the device, the related community and version are specified (--snmp-version='2c' --snmp-community='acme_ro').

This command would trigger a WARNING alarm if cpu utilization over 90% (--warning-cpu-load='90') and a CRITICAL alarm over 95% (--critical-cpu-load='95').

All the options as well as all the available thresholds can be displayed by adding the --help parameter to the command:

/usr/lib/centreon/plugins/centreon_acmepacket_snmp.pl \
    --plugin=network::acmepacket::snmp::plugin \
    --mode=system-usage \
    --help

Troubleshooting​

UNKNOWN: SNMP GET Request : Timeout​

If you get this message, you're probably facing one of theses issues:

  • The SNMP agent of the device isn't started or is misconfigured
  • An external device is blocking the request (firewall, ...)

UNKNOWN: SNMP GET Request : Cant get a single value.​

This error message often refers to the following issues:

  • The agent doesn't support the MIB used by the plugin
  • The targeted SNMP OID cannot be fetched because of insufficient privileges on the device. SNMP Agent must be capable of accessing to the enterprise branch: .1.3.6.1.4.1.9148
