Self-made python script to monitor Esxi underlying DELL hard disk (using python with its own module paramiko)
[root@localhost libexec] # cd / usr/local/nagios/libexec
[root@localhost libexec] # vi datadomain.py
#! / usr/bin/env python
Import paramiko
Import re
Import sys
# 0 ok; 1 warning; 2 critical; 3 unknown
Ssh = paramiko.SSHClient ()
Ssh.set_missing_host_key_policy (paramiko.AutoAddPolicy ())
Ip = "10.10.254.11"
User = "sysadmin"
Passwd = "1111111111111111"
Ssh.connect (ip,22,user,passwd)
Stdin,stdout,stderr = ssh.exec_command ("disk status")
Outmsg,errmsg = stdout.read (), stderr.read ()
Keyvalue=outmsg.find ('7')
If int (keyvalue)-1:
Print "Disk ok!"
Sys.exit (0)
Else:
Print "Disk goes wrong!"
Sys.exit (2)
Ssh.close ()
Script note: when keyvalue is equal to-1, the quantity is not 7, that is, there is a problem with the hard drive.
Add commands to commands.cfg first.
[root@localhost libexec] # vi / usr/local/nagios/etc/objects/commands.cfg
Define command {
Command_name datadomain
Command_line sudo $USER1 $/ datadomain.py
}
Add the following to nagios.cfg
[root@localhost libexec] # vi / usr/local/nagios/etc/nagios.cfg
Cfg_file=/usr/local/nagios/etc/objects/datadomain.cfg
Define hosts and services: create a new datadomain.cfg in / usr/local/nagios/etc/objects
[root@localhost libexec] # vi / usr/local/nagios/etc/objects/datadomain.cfg
Define host {
Use EMC DataDomain 2200
Host_name EMC DataDomain 2200
Alias EMC DataDomain 2200
Address 10.10.254.11
}
Define service {
Use generic-service
Host_name EMC DataDomain 2200
Service_description EMC DataDomain 2200
Check_command datadomain
Notifications_enabled 1
}
Then you must add the following to the templates.cfg
[root@localhost libexec] # vi / usr/local/nagios/etc/objects/templates.cfg
Define host {
Name EMC DataDomain 2200; The name of this host template
Use generic-host; This template inherits other values from the generic-host template
Check_period 24x7; By default, EMC DataDomain 2200 hosts are checked round the clock
Check_interval 5; Actively check the host every 10 minutes
Retry_interval 1; Schedule host check retries at 10 minute intervals
Max_check_attempts 10; Check each EMC DataDomain 2200 host 10 times (max)
Check_command check-host-alive; Default command to check EMC DataDomain 2200 hosts
Notification_period workhours; EMC DataDomain 2200 admins hate to be woken up, so we only notify during the day
; Note that the notification_period variable is being overridden from
; the value that is inherited from the generic-host template!
Notification_interval 120; Resend notifications every 2 hours
Notification_options djingheng r; Only send notifications for specific host states
Contact_groups admins; Notifications get sent to the admins by default
Register 0; DONT REGISTER THIS DEFINITION-ITS NOT A REAL HOST, JUST A TEMPLATE!
}
Add sudo permissions
[root@localhost libexec] # visudo
Nagios ALL= (ALL) NOPASSWD:/usr/local/nagios/libexec/datadomain.py
