Update: Trigger a User event from the VCSA command line

Disclaimer: This is not officially supported by VMware, please use at your own risk.

Recently I faced the challenge with a script running on a VCSA which executes some checks and in case something gets detected it has to trigger a vCenter alarm.

My solution is to log a user event which will be captured by an vCenter alert definition.

1. vCenter alert definition

as trigger manually enter (type): vim.event.GeneralUserEvent

2. The script which will log the user event

#!/usr/bin/python

#!/usr/bin/python

import sys
sys.path.insert(0, '/usr/lib/vmware/site-packages/')
from pyVim.connect import SmartConnect
from pyVmomi import vim
import ssl
import atexit

username = 'administrator@vsphere.local'
password = 'VMware1!'

v = sys.version_info
try:

        if sys.version_info[1] <7 or v.minor < 7:
                si = SmartConnect(host="localhost", user=username, pwd=password)
                content = si.RetrieveContent()
                ds = content.rootFolder
                log = si.content.eventManager.LogUserEvent(entity=ds, msg="Postgres Corruption detected")
        else:
                s = ssl.SSLContext(ssl.PROTOCOL_TLS)
                s.verify_mode = ssl.CERT_NONE
                si = SmartConnect(host="localhost", user=username, pwd=password, sslContext=s)
                content = si.RetrieveContent()
                ds = content.rootFolder
                log = si.content.eventManager.LogUserEvent(entity=ds, msg="Postgres Corruption detected")
except:
        print("Unexpected error:", sys.exc_info()[0])

Result:

The resulting alert can be catched by vROPs and trigger further events/ tickets.…

vCenter notification send push message using Prowl to iOS devices

I would like to receive push messages for triggered alerts from my vCenter. There is the possibility to execute a command when a alert has been triggered so I decided to write a script which will use Prowl to send push notification to my mobile apple device. I used Prowl already for other devices like my Homematic home automation system. It’s easy to use with an simple curl command. You can find a lot of good examples available by using Google.

Push notification service

You have to create an account on www.prowlapp.com and generate a new API key. The new API key has to be added to script (replace PLACE_YOUR_API_KEY_HERE with your API key).

Script:

This script is really basic and is only a proof of concept. I will extend and improve it over time.

root@vcenter [ ~ ]# mkdir bin
root@vcenter [ ~ ]#
