I'm trying to duplicate the following kstat code in jkstat:
# kstat -p cpu_stat:::execpgin
cpu_stat:0:cpu_stat0:execpgin 57553
cpu_stat:1:cpu_stat1:execpgin 53963
.
.
It doesn't look like you can use a filter to directly gather the kstat
information using jkstat. The filter's "getKstats()" method returns a Set of
Kstats, with the module, instance, and name variables populated, but the actual
Map of statistics is empty. So, in order to actually get the statistics, I had
to create the filter, get the Set of "empty" Kstats, then run "getKstat()" on
each of them to actually get the statistic data.
Is there a better way to do this? My java code is below:
<pre>
// Initialize JKstat and filter
JKstat jkstat = new JKstat();
KstatFilter ksf = new KstatFilter(jkstat);
ksf.addFilter("cpu_stat:::");
// Get the list of empty Kstats
Set <Kstat> vfilter = ksf.getKstats();
// Now iterate through them
Iterator kItr = vfilter.iterator();
while(kItr.hasNext()) {
Kstat kstat = (Kstat)kItr.next();
// Use empty Kstat module, instance, and name data to get the statistic
information
Kstat kstat2 =
jkstat.getKstat(kstat.getModule(),kstat.getInst(),kstat.getName());
Map <String, KstatData> kstat2Map = kstat2.getMap();
KstatData execpgin2Data = kstat2Map.get("execpgin");
System.out.println(kstat2.getTriplet() + ":execpgin: " +
(Long)execpginData2.getData());
}
</pre>
