How to check a service:port on another node

Hello Puppet folks,

I'm looking for ideas to implement inter-node connections/checks to my Puppet code.

For example: we have multiple Apache webservers connecting to several MariaDB servers, Memcached servers, .. and various other services. We have multiple administrative servers (ELK stack, Puppet master, Jenkins, ..) contacting/running agent services on other nodes.

I would like to run some kind of agent or command on each node to see if it can still connect to services(:port) on other nodes. Ideally all this information sits in hieradata (we use roles/profiles setup) and writes its output to Logstash/Elasticsearch.

Goal is not to check uptime of the services but more like firewall rules/ACLs configured by our network team. We don't have control over those rules or the changes they make ;-)

All suggestions or ideas are welcome.

Kind Regards,

What you need is a monitoring system (nagios, collectd) that should be configured by puppet.

Puppet has a lot resources for configuring nagios using exported resources.

Christian, Thanks for the reply. I'm using the collectd puppet forge module already to monitor http and mysql stuff. I'm not a network expert, what collectd plugin could i use to check service:port on other hosts?
