NEP Monitoring Core

Package nep-monitoring-core adds self-monitoring capabilities to a NetEye. It enables NetEye to:

  • Find the main components of the current Infrastructure

  • Monitor them using a predefined set of checks

This Package is the first of a series: it covers only NetEye Core module functionalities. To monitor other NetEye modules, other NEPs are required. This Package will also act as a common base for other NetEye Monitoring-related Packages, therefore it is required to successfully monitor other NetEye modules.

Minimum supported environment

This package can be installed on systems running the software described below. Systems with equivalent components are also suitable for installation.

Package requirements

Service and Host Template shipped with package nep-monitoring-core require the following nep:

  • nep-common

If the NetEye deployments that will receive Package nep-common is a clustered environment, additional preparations must be done.

Additional preparations for a Clustered NetEye Deployment

To allow nep-monitoring-core components to operate correctly, all Cluster node’s Configuration must be carefully edited to:

  • Allow icinga service user to access Icinga IDO database

  • Allow icinga service user to run a high privilege Check Plugin to read the current cluster state

To perform this configuration, run these commands on a Cluster Node as root user. Remember to update the contents ot variable nodes: it must contains the internal names of all Cluster Nodes (excluding Voting or Elastic Data-Only nodes). Internal names are the FQDN having .neteyelocal as domain part.

#Initializing variables
# Provide the internal name of all cluster nodes (excluding voting and data-only nodes)
# E.G.:
# nodes="clusternode1.neteyelocal clusternode2.neteyelocal clusternode3.neteyelocal"
nodes="<Node1 Internal name> <Node2 Internal name> <...> <NodeN Internal name>"
icinga_home=$(eval echo ~icinga)
monitoring_home=$(eval echo ~monitoring)

#Creating objects on all nodes
for node in $nodes ; do ssh $node "sudo -u icinga ssh-keygen -t rsa -N '' -f $icinga_home/.ssh/id_rsa <<< n"  ; done
for node in $nodes ; do ssh $node "useradd monitoring"  ; done
monitoring_home=$(eval echo ~monitoring)
for node in $nodes ; do ssh $node "install -d -m 700 -o monitoring -g monitoring $monitoring_home/.ssh"  ; done

#Creating authorized keys on local node
touch /home/monitoring/.ssh/authorized_keys
cat /dev/null > /home/monitoring/.ssh/authorized_keys
for node in $nodes ; do ssh $node "cat $icinga_home/.ssh/id_rsa.pub" >> $monitoring_home/.ssh/authorized_keys ; done

#Copying authorized keys on all nodes
for node in $nodes ; do scp "$monitoring_home/.ssh/authorized_keys" "$node:$monitoring_home/.ssh/authorized_keys" ; done
for node in $nodes ; do ssh $node "chmod 600 $monitoring_home/.ssh/authorized_keys" ; done
for node in $nodes ; do ssh $node "chown monitoring:monitoring $monitoring_home/.ssh/authorized_keys" ; done

#Adding sudoers permissions for icinga on local node
touch /etc/sudoers.d/icinga
cat /dev/null > /etc/sudoers.d/icinga
echo 'icinga ALL = NOPASSWD: /usr/sbin/crm_mon' > /etc/sudoers.d/icinga

#Copying sudores permissions to all nodes
for node in $nodes ; do scp /etc/sudoers.d/icinga $node:/etc/sudoers.d/icinga ; done
for node in $nodes ; do ssh $node "chmod 644 /etc/sudoers.d/icinga" ; done
for node in $nodes ; do ssh $node "chown root:root /etc/sudoers.d/icinga" ; done

Setup instructions

If all requirements are met, you can now install this package. To manually set up the nep-monitoring-core package, follow the instructions contained in manual-setup.md located in the root directory of the package. When the Package is installed, post-setup steps must be executed to monitor the current NetEye infrastructure.

Post-Setup steps

Package nep-monitoring-core has self-populating capabilities. To create the required monitoring objects, just run the automations provided by this Package.

  1. Run the following Import Sources

    • NetEye infrastructure endpoints Source

    • NetEye infrastructure child zones Source

  2. Run the following Sync Rules in the reported order:

    • NetEye infrastructure endpoints Rule

    • NetEye infrastructure child zones Rule

This will create the required objects for NetEye Monitoring. Then, the generated Host Objects’ properties must be updated to reflect the current configuration of the NetEye infrastructure:

  1. Open Director

  2. Locate Host Object NetEye Master zone Endpoint

  3. Edit Custom Property Installed modules, selecting all the installed NetEye modules

  4. If it is a Clustered NetEye deployment

    1. Search NetEye Cluster node inside the Host Objects: all cluster nodes will be found

    2. Edit Custom Property Local Services and select all the eventually installed NetEye Local services

After this, all the required services will be automatically assigned to the right Host Objects.

Then, the new configuration can be safely deployed.

Automatic Object’s update

Automations provided by this Package can be freely used to generate and refresh all the required monitoring objects. NetEye deployments are not updated often, but the automations can be eventually scheduled by the End User in the Jobs section of Director Automations.

Available Objects

Automations provided with this Package can take care of everything themselves. Therefore, is not suggested to the End User to manually use Objects from this Package that are not Import Sources or Sync Rules.

This section contains a description of all the Objects from this package that can be used to build your own monitoring environment.

Director Objects
