Systemd restarting

A while ago I had a service that would need to be restarted after it had a cool down of about 2 hours… I had a stanza that stated

Restart=always
RestartSec=7200

which was cool because it would just autorestart when it died. At the time the restart would work just fine after the cooldown. The catch that I ran in to was because of that timer, if I logged in and tried to start it when it was in a failed state, the service would hang. The fix for this is to issue the systemctl stop service command and the run the systemctl start service It was super annoying figuring this out so a good idea to keep track of it for later ;)

splunk hec python

before i had a splunk hec python bit that would do things to publish info into splunk from python. This kind of worked but it had a weird bug in it… that bug is fixed here.

#!/usr/bin/env python
import time
import requests
import urllib3
##turns off the warning that is generated below because using self signed ssl cert
urllib3.disable_warnings()

authToken="my token"
splunkhost="localhost"


def splunkHec(host, token, logdata):
  url='https://'+host+':8088/services/collector/event'
  authHeader = {'Authorization': 'Splunk '+token}
  r = requests.post(url, headers=authHeader, json=logdata, verify=False)



def main():
  while True:


    payload = {}
    payload.update({"index":"my_index"})
    payload.update({"sourcetype":"mysourcetype"})
    payload.update({"source":"mysource"})
    payload.update({"host":"myhost"})
    payload.update({"event":data})
    splunkHec(splunkhost, authToken, payload)

if __name__ == "__main__":
    main()
