Athonet ePC SNMP

Monitoring Connector Assets​

Monitored Objects​

The Monitoring Connector Athonet ePC SNMP collects metrics for:

  • aggregate
  • apns
  • interfaces (diameter, GA, GTPC, LTE)
  • license
  • lte

This table describes which metrics can be collected according to roles.

Collected Metrics​

Metric nameDescriptionUnit
aggregate.traffic.in.bytespersecondAggregate incoming trafficB/s
aggregate.traffic.out.bytespersecond Aggregate outgoing trafficB/s
hss.users.roaming.connected.countNumber of roaming users connected
hss.requests.authentication.countNumber of authentication requests
hss.location.updates.countNumber of location updates

Prerequisites​

To control your Athonet ePC equipments, the SNMP must be configured.

Setup​

  1. Install the Centreon Plugin on every Poller:
yum install centreon-plugin-Network-Athonet-Epc-Snmp
  1. On the Centreon Web interface in Configuration > Monitoring Connector Manager, install the Athonet ePC SNMP 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-Athonet-Epc-SNMP-Custom Host Template

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

MandatoryNameDescription
SNMPEXTRAOPTIONSConfigure your own SNMPv3 credentials combo

FAQ​

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_athonet_epc_snmp.pl \
    --plugin=network::athonet::epc::snmp::plugin \
    --mode=lte \
    --hostname=10.30.2.114 \
    --snmp-version='2c' \
    --snmp-community='athonet_ro' \
    --warning-users-connected='100' \
    --critical-users-connected='200' \
    --verbose

Expected command output is shown below:

OK: Lte traffic in: 0 B/s, traffic out: 0 B/s - connected users: 0, idle users: 0, active sessions: 0 - attach requests total: 0 success: 0 (100.00%) - pdn context activation requests total: 0 success: 0 (100.00%) - ue context release requests: 0, ue context release with radio lost requests: 0 - pdn context requests reject insufficent resources: 0, missing or unknown apn: 0, not subscribed: 0 | 'lte.traffic.in.bytespersecond'=0B/s;;;0; 'lte.traffic.out.bytespersecond'=0B/s;;;0; 'lte.users.connected.count'=0;0:100;0:200;0; 'lte.users.idle.count'=0;;;0; 'lte.sessions.active.count'=0;;;0; 'lte.requests.attach.success.count'=0;;;0;0 'lte.requests.attach.success.percentage'=100%;;;0;100 'lte.requests.pdn_context.activations.success.count'=0;;;0;0 'lte.requests.pdn_context.activations.success.percentage'=100%;;;0;100 'lte.requests.ue_context_release.total.count'=0;;;0; 'lte.requests.ue_context_release.radio_lost.count'=0;;;0; 'lte.requests.pdn_context.reject.insufficent_resources.count'=0;;;0; 'lte.requests.pdn_context.reject.no_apn.count'=0;;;0; 'lte.requests.pdn_context.reject.not_subscribed.count'=0;;;0;

    traffic in: 0 B/s, traffic out: 0 B/s

The command above monitors Athonet ePC LTE statistics (--plugin=network::athonet::epc::snmp::plugin --mode=lte) 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='athonet_ro').

This command would trigger a WARNING alarm if there are more than 100 connected users (--warning-users-connected='100') and a CRITICAL alarm for more than 200 (--critical-users-connected='200').

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_athonet_epc_snmp.pl \
    --plugin=network::athonet::epc::snmp::plugin \
    --mode=lte \
    --help

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: .1.3.6.1.4.1.35805.10
