choria/mcollective_agent_nettest — version 4.1.0 Aug 26th 2024
Choria Nettest agent
This is an agent that will execute a ping or remote connection test on mcollective hosts
I often find myself logging onto boxes to ping different sites to diagnose local or remote network issues, this means I can now just issue a single command and get results from anywhere I’m running mcollective.
Installation
This module depends on the Net::Ping Ruby gem which requires a C++ compiler
to build.
Usage
ICMP ping test:
$ mco nettest ping hostname
Do you really want to perform network tests unfiltered? (y/n): y
* [ ============================================================> ] 11 / 11
node1.example.net time = 0.429
node8.example.net time = 0.388
node5.example.net time = 0.686

middleware.example.net time = 2.697

Summary of RTT:
Min: 0.388ms Max: 16.455ms Average: 2.393ms
Finished processing 11 / 11 hosts in 85.76 ms
TCP connection test to port 8140:
$ mco nettest connect hostname 8140
Validator
The nettest agent supplies an fqdn validator which will validate if a string is a valid uri.
validate :fqdn, :nettest_fqdn
The nettest agent supplies a server address validator which will validate that a given string includes both a valid hostname and port number separated by a colon.
validate :serveraddress, :nettest_server_address
Data Plugin
The nettest agent also supplies a data plugin which uses the nettest agent to check if a connection to a fqdn at a specific port can be made. The data plugin will return 'true' or 'false' and can be used during discovery or any other place where the MCollective discovery language is used.
$ mco rpc rpcutil -S "Nettest('myhost', '8080').connect=true"
Mma Aggregate Plugin
The nettest agent supplies a mma aggregate plugin which will determine the minimum value, maximum value and average value of a set of inputs determinted in a DDL.
