Re: Metrics avgRequestsPerSecond and avgRequestsPerSecond from documentation gone?
Hi,
Yes, the documentation needs to be fixed, these attributes have been removed or
replaced.
* avgRequestsPerSecond -> requestTimes:meanRate. Please note that this is a
non-decaying simple average based on the total wall clock time elapsed since
the handler was started until NOW, and the total number of requests the handler
processed in this time.
* avgTimePerRequest = totalTime / requests (in nano-seconds). Please note that
the “totalTime” metric represents the aggregated elapsed time when the handler
was processing requests (ie. not including all other elapsed time when the
handler was just sitting idle). Perhaps a better name for this metric would be
“totalProcessingTime”.

Metrics avgRequestsPerSecond and avgRequestsPerSecond from documentation gone?
Greetings,
I'm using Solr 7.6 and have enabled JMX metrics.
I ran into this page:
https://lucene.apache.org/solr/guide/7_6/performance-statistics-reference.html#commonly-used-stats-for-request-handlers
Which mentions "avgRequestsPerSecond" and "avgTimePerRequest" and some
other attributes, which do not exist anymore in this version. I have an
older version(4) I spun up to have a look and they do exist in that version.
When getting info on a QUERY or UPDATE bean with name `requestTimes`, I get
this:
# attributes
%0 - 50thPercentile (double, r)
%1 - 75thPercentile (double, r)
%2 - 95thPercentile (double, r)
%3 - 98thPercentile (double, r)
%4 - 999thPercentile (double, r)
%5 - 99thPercentile (double, r)
%6 - Count (long, r)
%7 - DurationUnit (java.lang.String, r)
%8 - FifteenMinuteRate (double, r)
%9 - FiveMinuteRate (double, r)
%10 - Max (double, r)
%11 - Mean (double, r)
%12 - MeanRate (double, r)
%13 - Min (double, r)
%14 - OneMinuteRate (double, r)
%15 - RateUnit (java.lang.String, r)
%16 - StdDev (double, r)
%17 - _instanceTag (java.lang.String, r)
# operations
%0 - javax.management.ObjectName objectName()
%1 - [J values()
#there's no notifications
And it seems that none of the current values are actually a proper
replacement for the functionality these values used to offer.
How shall I go about getting this info now? Do I need to combine several
other metrics?
For completeness sake, my solr.xml, where I enabled JMX, is just the
default example from the documentation, with JMX added:
${host:}
${jetty.port:8983}
${hostContext:solr}
${zkClientTimeout:15000}
${genericCoreNodeNames:true}
${socketTimeout:0}
${connTimeout:0}
javax.net.ssl.keyStorePassword
javax.net.ssl.trustStorePassword
basicauth
zkDigestPassword
zkDigestReadonlyPassword
very_obvious_name_for_easy_reading_${jetty.port:8983}
Kind regards,
Koen De Groote
