A single missing space kept the alert alive.
Yodle's Zenoss monitoring was supposed to watch a process called Orkaudio. The team had deleted a separate tail process from monitoring, but the alerts kept coming.
The regular expression was too loose. Zenoss was looking for the word orkaudio, and a command using tail against an Orkaudio file still contained that word. The monitoring system found a match and treated the wrong process as the right one.
I told them to add a blank space after orkaudio in the expression. That would stop the tail command from matching. The change could be made from the process link in Zenoss.
I did not yet have a reply saying the alert had stopped. The space was the proposed correction, not a confirmed result.
There was a second problem in the same email. Links inside Zenoss alert messages pointed to port 8080, where nothing was listening. I pointed them toward the alerting template under settings. The message template, not the monitored process, controlled those links.
I had left Yodle after only a few weeks and was still answering questions about systems I had set up or changed during that short run.
I still knew where the configuration lived and why it behaved that way.
The mistake was small. The text around the process name still mattered because the loose rule matched the wrong command.
I sent two instructions back to the team: add the space and fix the alert template.
Both still had to be applied and tested.
