Performance Monitor Will Not Work

Question

The checkbox for Enable Performance Monitoring under the
debugging options tab in my CF8 install will not stay checked. Also
when I try to use the performance monitor to monitor CF8 it does
not work. Any ideas?

Answer 1

CF7 migrated to 8, applied fix as in kb402900 but no change
for me... cfstat can't find cfserver and no instance available in
perfmon
however i DID get it to work... it looks like the migration
process made .bak of all the xml files
the neo-metric.xml file had the format
<wddxPacket version="1.0">
<header />
<data>
<struct type="coldfusion.server.ConfigMap">
<var name="cfstat">
<string>true</string>
</var>
<var name="cfstatport">
<number>7999</number>
</var>
<var name="simpleLoad.sampleRate">
<string>5</string>
</var>
<var name="reqTimingWindow">
<string>10</string>
</var>
<var name="simpleLoad.constLoad">
<string>200</string>
</var>
<var name="simpleLoad.maxRequests">
<string>500</string>
</var>
<var name="cfperfmon.pullfreq">
<number>1.0</number>
</var>
<var name="simpleLoad.sampleSize">
<string>50</string>
</var>
<var name="cfperfmon">
<string>true</string>
</var>
</struct>
</data>
</wddxPacket>
and neo-metric.bak had the format
<wddxPacket version="1.0">
<header />
<data>
<struct type="coldfusion.server.ConfigMap">
<var name="simpleLoad.maxRequests">
<string>500</string>
</var>
<var name="simpleLoad.sampleRate">
<string>5</string>
</var>
<var name="reqTimingWindow">
<string>10</string>
</var>
<var name="simpleLoad.sampleSize">
<string>50</string>
</var>
<var name="simpleLoad.constLoad">
<string>200</string>
</var>
<var name="cfstat">
<string>true</string>
</var>
<var name="cfstatport">
<string>7999</string>
</var>
<var name="cfperfmon">
<string>true</string>
</var>
<var name="cfperfmon.pullfreq">
<number>1.0</number>
</var>
</struct>
</data>
</wddxPacket>
i noted that cfstat port in the old shows
<string>7999</string> and in the new cf8 it shows
<number>7999</number>
the entries are also in a different order (but i'm guessing
that shouldn't be a problem..right???)
i renamed neo-mertic.xml to neo-metric.cf8 (as backup) and
renamed neo-metric.bak (the cf7 version) to neo-metric.xml ,
restarted cfservice and now cfstat works and there's a jrun
instance in perfmon
you may be able to fix it by simply changing
<number></number> to <string></string> in
the existing version of neo-metrics.xml (unless the tag order does
count)...I didn't try that...
note: I had already applied the dll fixes so that may or may
not be required...
