Configure cron job to run every 15 minutes on Jenkins
Solution 1:
Your syntax is slightly wrong. Say:
*/15 * * * * command
|
|--> `*/15` would imply every 15 minutes.
*
indicates that the cron expression matches for all values of the field.
/
describes increments of ranges.
Solution 2:
1) Your cron is wrong. If you want to run job every 15 mins on Jenkins use this:
H/15 * * * *
2) Warning from Jenkins Spread load evenly by using ‘...’ rather than ‘...’
came with JENKINS-17311:
To allow periodically scheduled tasks to produce even load on the system, the symbol H (for “hash”) should be used wherever possible. For example, using 0 0 * * * for a dozen daily jobs will cause a large spike at midnight. In contrast, using H H * * * would still execute each job once a day, but not all at the same time, better using limited resources.
Examples:
-
H/15 * * * *
- every fifteen minutes (perhaps at :07, :22, :37, :52): -
H(0-29)/10 * * * *
- every ten minutes in the first half of every hour (three times, perhaps at :04, :14, :24) -
H 9-16/2 * * 1-5
- once every two hours every weekday (perhaps at 10:38 AM, 12:38 PM, 2:38 PM, 4:38 PM) -
H H 1,15 1-11 *
- once a day on the 1st and 15th of every month except December
Solution 3:
It should be,
*/15 * * * * your_command_or_whatever
