RE: Transform Swap Threshold Events to a more friendly format

I added this transform in zenoss 3.0.2, but it did not update the event message. It worked in 2.5.2.

Did you perform an upgrade? Try deleting it and adding it back in. After I did that it worked for me. (Im running Zenoss 3.1 upgraded from 2.5.2)

This is the one I'm currently using its a little better.

import re

# Extract the percent and free from the summary

m = re.search("threshold of [^:]+: current value ([\d\.]+)", evt.summary)

if m:

from Products.ZenUtils.Utils import convToUnits

isWindows = re.search("PagingFileTotalUsage", evt.eventKey)

if isWindows:

# windows displays percentage used

p = float(m.groups()[0])

totalBytes = device.os.totalSwap

usedBytes = totalBytes * (p / 100)

freeBytes = totalBytes - usedBytes

else:

freeBytes = float(m.groups()[0]) * 1024

totalBytes = device.os.totalSwap

usedBytes = totalBytes - freeBytes

p = (usedBytes / totalBytes) * 100

usedAmtGB = convToUnits(usedBytes)

freeAmtGB = convToUnits(freeBytes)

totalAmtGB = convToUnits(totalBytes)

evt.summary = "swap low: %3.1f%% used (%s used, %s free, %s total)" % (p,usedAmtGB,freeAmtGB,totalAmtGB)

evt.message = "swap low: %3.1f%% used (%s used, %s free, %s total)" % (p,usedAmtGB,freeAmtGB,totalAmtGB)
