Templates​

The Monitoring Connector Juniper M-Series Netconf brings a host template:

  • Net-Juniper-Mseries-Netconf-custom

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

Service AliasService TemplateService Description
CPUNet-Juniper-Mseries-Cpu-Netconf-customCheck CPU usage
HardwareNet-Juniper-Mseries-Hardware-Netconf-customCheck hardware
MemoryNet-Juniper-Mseries-Memory-Netconf-customCheck memory usage
OSPFNet-Juniper-Mseries-Ospf-Netconf-customCheck OSPF neighbors

The services listed above are created automatically when the Net-Juniper-Mseries-Netconf-custom host template is used.

Prerequisites​

The Netconf service must be enabled on the Juniper M-Series router, and the router must be configured to allow connections from the Centreon server or poller. A user account with the necessary rights to access Netconf data must also be created.

Installing the monitoring connector​

Pack​

The installation procedures for monitoring connectors are slightly different depending on whether your license is offline or online.

  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 > Connectors > Monitoring Connectors 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-routers-juniper-mseries-netconf
  1. Whatever the license type (online or offline), install the Juniper M-Series Netconf connector through the Configuration > Connectors > Monitoring Connectors 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-Routers-Juniper-Mseries-Netconf

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-Juniper-Mseries-Netconf-custom template to the host. A list of macros appears. Macros allow you to define how the connector will connect to the resource, and to customize the connector's behavior.
  4. Fill in the macros you want. Some macros are mandatory.
MacroDescriptionDefault valueMandatory
NETCONFEXTRAOPTIONSAny 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
FILTERSNMPINDEXFilter BGP peer by SNMP index
FILTERLOCALADDRESSFilter BGP peer by local address
FILTERPEERADDRESSFilter BGP peer by peer address
FILTERRIBNAMEFilter BGP RIB by RIB name
WARNINGBGPPEERDETECTEDWarning threshold for number of BGP peers detected
CRITICALBGPPEERDETECTEDCritical threshold for number of BGP peers detected
WARNINGBGPPEERRIBPREFIXESACTIVEWarning threshold for number of active prefixes in BGP peer RIB

WARNINGBGPPEERTRAFFICINWarning threshold for BGP peer traffic in
CRITICALBGPPEERTRAFFICINCritical threshold for BGP peer traffic in
WARNINGBGPPEERTRAFFICOUTWarning threshold for BGP peer traffic out
CRITICALBGPPEERTRAFFICOUTCritical threshold for BGP peer traffic out
WARNINGRIBSTATUSDefine the conditions to match for the status to be WARNING. You can use the following variables: %{localAddr}, %{localAs}, %{peerAddr}, %{peerAs}, %{peerState}, %{ribName}, %{sendState}
CRITICALRIBSTATUSDefine the conditions to match for the status to be CRITICAL. You can use the following variables: %{localAddr}, %{localAs}, %{peerAddr}, %{peerAs}, %{peerState}, %{ribName}, %{sendState}
CRITICALSTATUSDefine the conditions to match for the status to be CRITICAL (default: '%{peerState} !~ /established/i'). You can use the following variables: %{localAddr}, %{localAs}, %{peerAddr}, %{peerAs}, %{peerState}%{peerState} !~ /established/i
WARNINGSTATUSDefine the conditions to match for the status to be WARNING. You can use the following variables: %{localAddr}, %{localAs}, %{peerAddr}, %{peerAs}, %{peerState}
EXTRAOPTIONSAny extra option you may want to add to the command (a --verbose flag for example). All options are listed here.
  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_juniper_mseries_netconf.pl \
	--plugin=network::juniper::mseries::netconf::plugin \
	--mode=rsvp \
	--hostname=10.0.0.1  \
	--filter-name='' \
	--filter-type='' \
	--warning-rsvp-sessions-detected='' \
	--critical-rsvp-sessions-detected='' \
	--warning-status='' \
	--critical-status='%\{lspState\} !~ /up/i' \
	--warning-rsvp-session-lsp-traffic='' \
	--critical-rsvp-session-lsp-traffic=''

The expected command output is shown below:

OK: detected: 29162 All RSVP sessions are ok | 'rsvp.sessions.detected.count'=29162;;;0; 'rsvp1#rsvp.session.lsp.traffic.bytespersecond'=22122B/s;;;; 'rsvp2#rsvp.session.lsp.traffic.bytespersecond'=603B/s;;;;

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_juniper_mseries_netconf.pl \
	--plugin=network::juniper::mseries::netconf::plugin \
	--list-mode

The plugin brings the following modes:
