Nearly Random, Uncorrelated Server Load Average Spikes

Glad you figured it out already.
What's regarding instrumentation, I found it very helpful once I had basic monitoring data available for all my servers. I'm still sticking to the solution, I'm knowing and using for many years now(check_mk, open source of course), as it is easy to handle, flexible to extend and with thousands of check plugins ready at hand if needed and lots of features available if you need to do more. So you have the basic metrics of your equipment in reach.
Some examples of many basic graphs I which you get ready configured out of the box:
Network Interface Usage
Memory/Swap Usage
Filesystem grow and trending
So it's just a few clicks away to check and you'll get informed about all the basic stuff(disk full, memory full, cpu overloaded, network errors, ...), so you do not have to care for yourself in case of trouble and often you'll notice anomalies before it get's critical.
There maybe a lot of hot stuff out there like prometheus, netdata(demo), grafana(demo), ... but that far exceeds my needs and costs me too much - in terms of time and energy to get acquainted with - which I rather invest in other areas.

Hi ,
I am using 48 CPU sunOS server at my work.

Right now it is configured as 48. So it does mean that each CPU can take maximum one proces and no processe is waiting.

gpiv_process-chain
GPIV_PROCESS-CHAIN(1) General Commands Manual GPIV_PROCESS-CHAIN(1) NAME
gpiv_process-chain - Processes a pipe of Gpiv-tool command's. SYNOPSIS
gpiv_process-chain [-af string] [-h | -help] [-n | -none] [-c | -clean] [-fik] [-p | -print] [-pf -string] [-proc_*] [-t format] [-v | -version] filename DESCRIPTION
Gpiv_process-chain processes a pipe of gpiv commands. Image evaluation/interrogation with gpiv_rr is always included, image recording may be prepended before interrogation, validation and post-processes may be appended to the chain. The filename represents the name of the image to be evaluated. The file naming conventions are idententic to the output of the individual Gpivtools programs: in case the output are (validated/scaled) PIV data, the data will be directed to filename.piv, with -proc_vorty the output will be called filename.vor, with -proc_nstrain the output will be called filename.nstr and, finally, with with -proc_sstrain the output will be called filename.sstr. This program does not use the parameter resources from libgpiv. Options -af string Append string to file-base name. -h | --help On-line help. -n | --none Suppresses real execution. -c | -clean Cleans up: removes raw image data and header. -fik Use fi-keyline for filtering gpiv parms from README. -p | --print Prints parameters, command line options and input and output filenames to stdout. -pf string Prepend string to file-base name. -proc_* Defines processes to be included in the chain. * is substituted by: imgrec, valid, scale, manipiv, flipx, flipy, revert, rot90, rot180 and vorty or nstrain or sstrain. Vorty, nstrain and sstrain may not be used in combination with -t gpi. -t format Image type or format: hdf (.hdf), dav (.IMG) or a type as defined by ImageMagic's convert. Default is raw binary image (.r). -v | --version Prints version information to standard output, then exits successfully. filename Input image filename. Format may be: .r, .hdf (hdf), .IMG (davis), .png, .gif, .tif or.bmp. EXAMPLES
invoking: 'gpiv_process-chain -proc_valid -proc_scale testfile.png' will actually perform: gpiv_rr < image.png | gpiv_errvec > testfile.piv invoking: 'gpiv_process-chain -proc_imgrec -proc_valid -proc_scale testfile.png' will do: gpiv_recimg | gpiv_rr | gpiv_errvec | gpiv_scale > testfile.piv SEE ALSO
