NSCA

NSCA (Nagios Service Check Acceptor) is a means by which host and check results can be passed into Opsview Monitor from a remote source.

 

Installation

The opsview-nsca package is available for download from:

OS Source
CentOS6/RHEL6 https://s3-eu-west-1.amazonaws.com/opsview-customers/NSCA/opsview-nsca-6.0.0.201902071733-1.ct6.x86_64.rpm
CentOS7/RHEL7/OL7 https://s3-eu-west-1.amazonaws.com/opsview-customers/NSCA/opsview-nsca-6.0.0.201902071733-1.ct7.x86_64.rpm
CentOS8/RHEL8/OL8 https://downloads.opsview.com/opsview-support/opsview-nsca-6.2.0-1.el8.x86_64.rpm
Ubuntu14 (Trusty) https://s3-eu-west-1.amazonaws.com/opsview-customers/NSCA/opsview-nsca_6.0.0.201902071733-1trusty1_amd64.deb
Ubuntu16 (Xenial) https://s3-eu-west-1.amazonaws.com/opsview-customers/NSCA/opsview-nsca_6.0.0.201902071733-1xenial1_amd64.deb

After installing the package on either the Orchestrator and/or Collectors you may need to amend your firewall to allow port 5667 through.

 

Configuration

If /opt/opsview/nsca/etc/nsca.cfg did not previously exist, a password is randomly generated and put into the file. If you need to specify the password, edit this file and set password (and any other settings) as appropriate for your needs.
The NSCA daemon will not be started automatically. You need enable the configuration and reload opsview_watchdog:

cp /opt/opsview/watchdog/etc/services/opsview-nsca.conf.dis /opt/opsview/watchdog/etc/services/opsview-nsca.conf
/opt/opsview/watchdog/bin/opsview-monit reload

The NSCA daemon will then be started and available for connections.
