To provide a long term analysis of one server, a short extract can be created to retreive specific information from the performance database. By logging on to the ZMAP userid, create the following file called "UCDSYS ESAEXTR" on the "A" disk. Note that this will extract the LINUX CPU information for node S11R20RA. Modify to meet your reporting requirements.
EXTRACT: TITLE = 'Linux CPU by Time &USERID' TITLE = '*Labels NODE TOTCPU usercpu syscpu iowait kernel' INTERVAL='IN' X ='STOPTIME' Y = 'NODE' Y ='UCDSYS.TOTCPU ' Y ='UCDSYS.USERPCT' Y ='UCDSYS.SYSTPCT' Y ='UCDSYS.IOWAIT ' Y ='UCDSYS.KRNLCPU' criteria='NODE=S11R20RA'
Once this extract is created, the performance database has sets of files for each day, limited to disk space you have provided. Running the following would provide any information in the performance database for the server that is listed, in this case S11R20RA for the months of october, november and december for year 2013.
ESAEXTR 20131* (PARM UCDSYS
The resulting information is in file: "20131 EXTRACT"
The extract function can be used to extract data from a specific month using the following format:
esaextr (parm ucdsys month 12/13to extract from december in 2013. This will produce a file called "MONTH EXTRACT" that contains the results of your request.
To find available history data, issue "FILELIST ESASYS * D".
Please logoff from ZMAP when done to ensure that normal nightly operations occur.
