The following script can verify any probe for which controller has generated an alarm like the following:
?
Jun 3 10:59:48:951 [3086726848] Controller: Probe 'spooler' FAILED to start, file check determines changes in the probe?
?
?
Step 1: Create script
?
In Nas auto operator->Scripts section, create a new script with following contents:
?
-- Start of script
al = alarm.list() -- Get alarm list

re = "%p%a+%d*_*%a*%d*%p" -- Regex to match probe name with alpha, numbers and underscore

if al ~= null then
for i = 1,#al do
if al[i].prid == "controller" then -- First, filter to get alarms from controller probe only

if string.match(al[i].message,"FAILED to start") then -- Second, filter to get controller alarms with specific text i-e "FAILED to start"

probe = string.gsub(string.match(al[i].message,re),"'","") -- Get probe name from alarm message and then remove quotes from probe name to use in probe_verify callback
--print(al[i].message.."! Probe-> "..probe) -- View alarms with probe names which failed to start

addr = "/"..al[i].domain.."/"..al[i].hub.."/"..al[i].robot.."/".."controller" -- Build Nimsoft address
-- printf("/"..al[i].domain.."/"..al[i].hub.."/"..al[i].robot.."/".."controller".."<->Probe="..al[i].prid) -- Print Nimsoft address(es)


-- Now run the probe_verify callbacks on each probe which FAILED to start

local args = pds.create()
pds.putString(args,"name",probe)
nimbus.request(addr,"probe_verify",args)
nimbus.request(addr,"probe_activate",args)
pds.delete(args)
sleep (100) -- A little delay between each probe callback
end
end
end
end?
-- End of script
?
?
Step 2: Setup nas profile
?
- Setup a nas auto operator profile with following settings in?
a- matching criteria:
severity = major
probe = controller
matching text =?/.*Probe.*\sFAILED\sto\sstart.*/
?
b- Action type: script
Script = choose the script created in step 1from drop down list
?
?
c- Action Mode: On OVerdue age with ?your desired time settings
?
?
Click Ok and Apply to save changes and restart nas probe. Now, the above settings will automatically verify probes if they failed to start due to cheksum change detection.
