Patton SmartNode SNMP

Connector dependencies​

The following monitoring connectors will be installed when you install the Patton SmartNode SNMP connector through the Configuration > Monitoring Connector Manager menu:

Pack assets​

Templates​

The Monitoring Connector Patton SmartNode SNMP brings a host template:

  • Net-Patton-Smartnode-SNMP-custom

The connector brings the following service templates (sorted by the host template they are attached to):

Service AliasService TemplateService Description
CallNet-Patton-Smartnode-Call-SNMP-customCheck calls
SystemNet-Patton-Smartnode-System-SNMP-customCheck system health

The services listed above are created automatically when the Net-Patton-Smartnode-SNMP-custom host template is used.

Discovery rules​

Host discovery​

Rule nameDescription
SNMP AgentsDiscover your resources through an SNMP subnet scan. You need to install the Generic SNMP connector to get the discovery rule and create a template mapper for the Net-Patton-Smartnode-SNMP-custom host template.

More information about discovering hosts automatically is available on the dedicated page.

Collected metrics & status​

Here is the list of services for this connector, detailing all metrics and statuses linked to each service.

NameUnit
gateway#gateway.calls.connected.countcount
gateway#gateway.calls.ongoing.countcount
gateway#gateway.calls.accumulated.countcount
isdn#isdn.calls.connected.countcount
isdn#isdn.calls.ongoing.countcount
isdn#isdn.calls.accumulated.countcount

Prerequisites​

SNMP Configuration​

The SNMP agent must be configured and activated on the host. Please refer to the official documentation from the manufacturer/publisher.

Network flow​

The target resource must be reachable from the Centreon poller on the UDP/161 SNMP port.

Installing the monitoring connector​

Pack​

  1. If the platform uses an online license, you can skip the package installation instruction below as it is not required to have the connector displayed within the Configuration > Monitoring Connector Manager menu. If the platform uses an offline license, install the package on the central server with the command corresponding to the operating system's package manager:
dnf install centreon-pack-network-patton-smartnode-snmp
  1. Whatever the license type (online or offline), install the Patton SmartNode SNMP connector through the Configuration > Monitoring Connector Manager menu.

Plugin​

Since Centreon 22.04, you can benefit from the 'Automatic plugin installation' feature. When this feature is enabled, you can skip the installation part below.

You still have to manually install the plugin on the poller(s) when:

  • Automatic plugin installation is turned off
  • You want to run a discovery job from a poller that doesn't monitor any resource of this kind yet

More information in the Installing the plugin section.

Use the commands below according to your operating system's package manager:

dnf install centreon-plugin-Network-Patton-SmartNode-Snmp

Using the monitoring connector​

Using a host template provided by the connector​

  1. Log into Centreon and add a new host through Configuration > Hosts.
  2. Fill in the Name, Alias & IP Address/DNS fields according to your resource's settings.
  3. Apply the Net-Patton-Smartnode-SNMP-custom template to the host.

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

MacroDescriptionDefault valueMandatory
SNMPEXTRAOPTIONSAny extra option you may want to add to every command (a --verbose flag for example). All options are listed here.
  1. Deploy the configuration. The host appears in the list of hosts, and on the Resources Status page. The command that is sent by the connector is displayed in the details panel of the host: it shows the values of the macros.

Using a service template provided by the connector​

  1. If you have used a host template and checked Create Services linked to the Template too, the services linked to the template have been created automatically, using the corresponding service templates. Otherwise, create manually the services you want and apply a service template to them.
  2. Fill in the macros you want (e.g. to change the thresholds for the alerts). Some macros are mandatory (see the table below).
MacroDescriptionDefault valueMandatory

  1. Deploy the configuration. The service appears in the list of services, and on the Resources Status page. The command that is sent by the connector is displayed in the details panel of the service: it shows the values of the macros.

How to check in the CLI that the configuration is OK and what are the main options for?​

Once the plugin is installed, log into your Centreon poller's CLI using the centreon-engine user account (su - centreon-engine). Test that the connector is able to monitor a resource using a command like this one (replace the sample values by yours):

/usr/lib/centreon/plugins/centreon_patton_smartnode.pl \
	--plugin=network::patton::smartnode::snmp::plugin \
	--mode=system \
	--hostname=10.0.0.1 \
	--snmp-version='2c' \
	--snmp-community='my-snmp-community'  \
	--warning-memory-usage='' \
	--critical-memory-usage='' \
	--warning-memory-usage-free='' \
	--critical-memory-usage-free='' \
	--warning-memory-usage-prct='' \
	--critical-memory-usage-prct='' \
	--warning-cpu-average='' \
	--critical-cpu-average='' \
	--warning-core-cpu-utilization='' \
	--critical-core-cpu-utilization='' \
	--warning-core-cpu-utilization-1m='' \
	--critical-core-cpu-utilization-1m='' \
	--warning-core-cpu-utilization-5m='' \
	--critical-core-cpu-utilization-5m='' \
	--warning-probe-temperature='' \
	--critical-probe-temperature=''

The expected command output is shown below:

OK: 85144 % All CPU usages are ok All memory usages are ok All temperatures are ok | 'cpu.utilization.percentage'=85144%;;;0;100 'cpu1#core.cpu.utilization.percentage'=54920%;;;0;100 'cpu2#core.cpu.utilization.percentage'=67323%;;;0;100 'cpu1#core.cpu.utilization.1m.percentage'=62955%;;;0;100 'cpu2#core.cpu.utilization.1m.percentage'=62037%;;;0;100 'cpu1#core.cpu.utilization.5m.percentage'=49827%;;;0;100 'cpu2#core.cpu.utilization.5m.percentage'=58223%;;;0;100 'memory1#memory.usage.bytes'=23358B;;;0;memory_total_bytes 'memory2#memory.usage.bytes'=4661B;;;0;memory_total_bytes 'memory1#memory.free.bytes'=23634B;;;0;memory_total_bytes 'memory2#memory.free.bytes'=64023B;;;0;memory_total_bytes 'memory1#memory.usage.percentage'=87361%;;;0;100 'memory2#memory.usage.percentage'=47754%;;;0;100 'temperature1#probe.temperature.celsius'=42022C;;;0;100 'temperature2#probe.temperature.celsius'=97036C;;;0;100

Troubleshooting​

Please find the troubleshooting documentation for Centreon Plugins typical issues.

Available modes​

In most cases, a mode corresponds to a service template. The mode appears in the execution command for the connector. In the Centreon interface, you don't need to specify a mode explicitly: its use is implied when you apply a service template. However, you will need to specify the correct mode for the template if you want to test the execution command for the connector in your terminal.

All available modes can be displayed by adding the --list-mode parameter to the command:

/usr/lib/centreon/plugins/centreon_patton_smartnode.pl \
	--plugin=network::patton::smartnode::snmp::plugin \
	--list-mode

The plugin brings the following modes:

ModeLinked service template
call [code]Net-Patton-Smartnode-Call-SNMP-custom
system [code]Net-Patton-Smartnode-System-SNMP-custom

Available options​

Generic options​

All generic options are listed here:

Variables must be written either %{variable} or %(variable). Example: adding --filter-perfdata-adv='not (%(value) == 0 and %(max) eq "")' will remove all metrics whose value equals 0 and that don't have a maximum value.
--explode-perfdata-maxCreate a new metric for each metric that comes with a maximum limit. The new metric will be named identically with a '_max' suffix). Example: it will split 'used_prct'=26.93%;0:80;0:90;0;100 into 'used_prct'=26.93%;0:80;0:90;0;100 'used_prct_max'=100%;;;;
