    I am trying to find out what the allowed valued for counter types are in Introscope.

    In the windows Perfmon Epagent supplied by CA Wiley it uses metric type=LongCounter I was hoping to find what other datatypes are allowed.

    Googling for this comes up with some links which must be out of date and I can't find them on the current site

    There is a file named EPAgent8.x.x.xGuide.pdf and it states the following:

    XML format for metric data
    Where the “simple” format limits the Introscope metric types, XML style format
    allows the plug-in to report additional information, such as Introscope metric
    name, Introscope metric type, and value, as in the following example:
    <metric type="LongCounter" name="Resource Usage|File IO:diskWrites"
    value="37" />
    <metric type="StringEvent" name="Apache Errors:LastErrorString"
    value="ERROR: Apache shutdown unexpectedly" />

    XML format guidelines:
    This allows full support of Introscope data types as well as equals signs in both
    metric names and values.

    The “type” attribute of a metric must be one of the following:

    - PerIntervalCounter—the value is a rate "per interval" where the interval can
    change. These metrics are aggregated over time by summing the values.
    For example, if there were 10 method invocations per 15 seconds followed
    by 15 method invocations per 15 seconds, then aggregating to 30 seconds
    would result in "25 method invocations per 30 seconds".
    - IntCounter—int values can go up and down
    - IntAverage—int value that is averaged over time
    - IntRate—the value is a per second rate. These metrics are aggregated over
    time by taking the average of the values.
    - LongCounter—long values can go up and down
    -LongAverage—long value that is averaged over time
    - StringEvent—represents a type which periodically generates Strings. This
    recorder does not have a notion of current value; it merely reports events
    in the order in which they are reported to it.
    - Timestamp—a type which generates successively increasing timestamps.

    The comparison is case-insensitive (to make it easy for the plug-in writer). If
    a numeric type is supplied, but the value is non-numeric, nothing is reported
    to Introscope and an error will be logged by the EPAgent.

    Is this what you are looking for?
