I have the following code which should put all of a host's services in downtime, but I'm getting an error. Can you please help?

Code: Select all

#! /usr/local/bin/python2.7
import time

host = "myhost.mathworks.com"
CommandFile = "/usr/local/nagios/var/rw/nagios.cmd"

with open(CommandFile,"a") as nagiosCmd:
	now = int(time.time())
	later = now + 7200
	commandString = "[" + str(now) + "] SCHEDULE_HOST_SVC_DOWNTIME;" + host + ";" + str(now) + ";" + str(later) + ";1;0;
0;nagiosadmin;Host being retired\n"
	print (commandString)
	nagiosCmd.write(commandString)

This produces an error in nagios.log when it runs.

Which version of Nagios XI are you using? I can't reproduce this with 5.4.1. All my services go into downtime correctly according to nagios.log:

Code: Select all

Can you also share the output of:

Code: Select all

ls -al /usr/local/nagios/var/rw/

Nagios XI 2014R2.0

Hmm, i'm also unable to replicate this on my 2014r2.0 machine. Are you certain the host with the name "myhost.mathworks.com" exists on this system, or are you using this script generically with different hosts passed as arguments? Can you tell me how you're running this command? I copied your script and ran it as the root user like so:

Code: Select all

python script.py

Can you PM me a system profile? From the Nagios XI GUI, you can gather a profile via Admin -> System Profile -> Download Profile.
