Missing Event Handler
-
I created a scheduled event and a corresponding event handler; then recently noticed it wasn't firing. Looking at the event handler, I saw there was no event handler. Puzzled, I created a new event handler, but when I clicked "save" it rejected it for an existing XID.
When I do an export, I see the event handler, but in not the Event Handler page. Unfortunately, it is also failing to execute.
Here is the JSON for the Scheduled Event and the Event Handler:
{ "eventHandlers":[ { "eventType":{ "sourceType":"SCHEDULED", "XID":"SE_get_forecast" }, "xid":"EH_get_forecast", "handlerType":"PROCESS", "activeProcessCommand":"get_forecast.bash", "activeProcessTimeout":60, "inactiveProcessCommand":"", "inactiveProcessTimeout":15, "alias":"Get forecast", "disabled":true } ], "scheduledEvents":[ { "xid":"SE_get_forecast", "alarmLevel":"NONE", "scheduleType":"HOURLY", "activeCron":"0 0\/5 * * * ? *", "activeDay":0, "activeHour":0, "activeMinute":0, "activeMonth":11, "activeSecond":0, "activeYear":2017, "alias":"Get Weather Forecast", "disabled":false, "inactiveCron":"", "inactiveDay":0, "inactiveHour":0, "inactiveMinute":0, "inactiveMonth":11, "inactiveSecond":0, "inactiveYear":2017, "returnToNormal":false } ] } -
Hi Aldo,
I imported it without issue. Can you try clearing your browser cache and deleting your Mango/work/jsp directory?
Whatever the display issue, it's probably not executing because
"disabled":truein the configuration you posted. -
@phildunlap said in Missing Event Handler:
because
"disabled":trueUh, yeah. chuckles.... I tinkered with the the config in hopes of triggering it just right, and that's one of the parameters I changed. Before I shared it. But after I saw it fail. ;-)
On the less bonehead note, clearing the browser or the work directory did not seem to change anything.
FWIW this server was recently upgraded from 2.8 to 3.2, if that tells you anything.
-
Very odd. In frustration, I added another event handler, with the same parameters. It saved, executed, and shows in the Event Handlers page — but not the original! (which I have not deleted)
{ "eventHandlers":[ { "eventType":{ "sourceType":"SCHEDULED", "XID":"SE_get_forecast" }, "xid":"EH_get_forecast", "handlerType":"PROCESS", "activeProcessCommand":"false", "activeProcessTimeout":60, "inactiveProcessCommand":"", "inactiveProcessTimeout":15, "alias":"Get forecast", "disabled":false }, { "eventType":{ "sourceType":"SCHEDULED", "XID":"SE_get_forecast" }, "xid":"EH_get_forecast2", "handlerType":"PROCESS", "activeProcessCommand":"\/usr\/lib\/ia3-util\/get_forecast.bash", "activeProcessTimeout":60, "inactiveProcessCommand":"", "inactiveProcessTimeout":15, "alias":"Get Forecast", "disabled":false } ], "scheduledEvents":[ { "xid":"SE_get_forecast", "alarmLevel":"NONE", "scheduleType":"HOURLY", "activeCron":"0 0\/5 * * * ? *", "activeDay":0, "activeHour":0, "activeMinute":15, "activeMonth":11, "activeSecond":0, "activeYear":2017, "alias":"Get Weather Forecast", "disabled":false, "inactiveCron":"", "inactiveDay":0, "inactiveHour":0, "inactiveMinute":0, "inactiveMonth":11, "inactiveSecond":0, "inactiveYear":2017, "returnToNormal":false } ] } -
Hmm. Event handlers were decoupled from event detectors in that time, so that tells me that Upgrade18 might not have occurred entirely correctly in your case. Do you have an Upgrade18 log in your Mango/logs? Did you get an error to your console when it was performing this upgrade?
-
Didn't catch any errors during the actual upgrade, and no file exists by that name. However, there is this in the logs:

Also, that server quickly ran out of space and needed additional storage added, causing these errors in the log:
