Hi,

Centreon provides plugin for Elasticsearch and Graylog. Does Centreon plan a plugin for Splunk ?

Thanks

Hi, 


Indeed, we would love to have such​ Plugin. Let’s connect and see how we can mutually help.

Hi,

Don’t have the product yet, just a POC planned.

Hi,
Meanwhile, during the POC, we made a Python script to retrieve the number of results from a query sent to SPLUNK (Like Graylog plugin). This may be a start for a Centreon plugin.

Commande :
python3.6 /usr/lib64/nagios/plugins/check_splunk_api.py --hostname='XXX.XXX.XXX.XXX' --api_username='USERNAME' --api_password='PASSWORD' --port=8089  --query='QUERY' --timeframe='-15min' --warning_query_matches='5' --critical_query_matches='10'
 

Script :

from __future__ import print_function
from mailbox import _mboxMMDFMessage
from xml.dom import minidom
from future import standard_library
standard_library.install_aliases()
import sys, getopt, time, httplib2, argparse
import urllib.request, urllib.parse, urllib.error

# Get arguments
parser = argparse.ArgumentParser(description='Centreon check Splunk')
parser.add_argument("--hostname", help="IP splunk server")
parser.add_argument("--port", help="Port splunk server",default=8089)
parser.add_argument("--api_username", help="username")
parser.add_argument("--api_password", help="password")
parser.add_argument("--query", help="Search request")
parser.add_argument("--timeframe", help="time")
parser.add_argument("--warning_query_matches", type=int, help="Warning alert")
parser.add_argument("--critical_query_matches", type=int, help="Critical alert")

Hi, 

Thanks for the update.

Would it be possible to book a slot to discuss how we can benefit from this POC period to deliver an official centreon plugin? We can do something quickly.

 

Reach me @ sbomm@centreon.com if you’re interested in such meeting.

​​​​Best,
