Hey Guy,  
I have a really strange problem : I have 13 servers with the same client.json config (installed using saltstack not manually). On all these servers, I monitor apache2 proc :

cat check\_apache.json

{

“checks”: {

“check\_apache”: {

```
"handlers": [

	"mailer"

],

"command": "/etc/sensu/plugins/processes/check-procs.rb -p '/usr/sbin/apache2' -w 40 -c 50",

"interval": 60,

"occurrences": 5,

```

“subscribers”: [“apache”]

}

}

}

From one server, I keep received a alert email and a recover email at the same time for this service

alarm example :

CheckProcs CRITICAL: Found 0 matching processes; cmd //usr/sbin/apache2/

Host: ads-web9

Timestamp: 2014-04-18 15:35:35 +0000

Address: 127.0.0.1

Check Name: check\_apache

Command: /etc/sensu/plugins/processes/check-procs.rb -p ‘/usr/sbin/apache2’ -c 50

Status: 2

Occurrences: 1

If I rename the client name in client.json the old name and the new name magically in the client list. And I only receive alert from the old name. there is no other machine.

Is There a cache on the server that I can delete ?

Regards,

---
