Power Navigator Host Code Customization

pn.config options

nmonopts="-t -I 0.02" ext_data_collect="T" admin_data_collect="T" transfer_script_cmd="/usr/local/mpg/transfer_script.sh -c /usr/local/mpg/transfer_cp.config" transfer_current_cmd="/usr/local/mpg/transfer_current.sh -c /usr/local/mpg/transfer_cp.config" truncate_days="180" ext_data_truncate_days="90" purge_top_days="70" nmondaystokeep="7" compressdatafile="nocopy"


Power Navigator Host Code Customization

pn.config options nmonopts="-t -I 0.02"

-t –I 0.02 Power Navigator uses the NMON external data collection facility to collect PS data in sync with the NMON collection. To start collection PS data, set the following to “T”. This data is recorded in the mpgdata3.hostname file ext_data_collect="T" By default Power Navigator collect file system data once a week on Sunday. To stop collect this data, set the following to “F”. This data is stored in the mpgdata4.hostname file. Details regarding this collection can be changed in the pnadcp.config file. admin_data_collect="T"


Power Navigator Host Code Customization pn.config options (continued)

Power Navigator can be configured to transfer the data needed for the client to a central location. Either a share drive or an AIX/Linux system with Samba installed. Then the Windows Client maps a drive to have current access to the data. The transfer information containing the method (ftp, sftp, cp, scp) and the location for the transfer is stored in a file called trans-fer_xx.config. The ‘xx’ is the method. Below is an example of using ‘cp’ to transfer the data. This data is transferred once per day at around 4am. transfer_script_cmd="/usr/local/mpg/transfer_script.sh -c /usr/local/mpg/transfer_cp.config" The following parameter configures Power Navigator to transfer the mpg-data2_current.hostname file to the central location. This is todays NMON file up to the lase 5 minutes. Power Navigator uses the NMON external data collection feature to transfer this file every 5 minutes. transfer_current_cmd="/usr/local/mpg/transfer_current.sh -c /usr/local/mpg/transfer_cp.config" By default, Power Navigator keeps 366 days of NMON data in the mpg-data2.hostname file. Once a month Power Navigator will archive the data to a file called mpgdata2.archive.hostname.gz. Below is an example to set the ar-chive date to 180 days. truncate_days="180" Power Navigator archive the mpgdata3.hostname file once a month. The default is 90 days. The parameter below is use to change the date. ext_data_truncate_days="90" Top process data can be collected by setting the nmonopts parameter using the –t option. This function is used mainly for problem determination. After 90 days (default), the top data is deleted when merged into mpgdata2.hostname. The example below changes that to 70 days purge_top_days="70" In order to save space, the daily NMON data is GZed every night and then de-leted after 7 days (default). This can be change via the following parame-ter. nmondaystokeep="7"


Power Navigator Host Code Customization pnadcp.config options

The Admin Data Collection Process in Power Navigator collects data once a week on Sundays (by default) regarding file systems space utilization and keeps the data historically. The current defaults and below. You can changes these defaults using the following parameters: TopDFCnt=20 # Number of Largest Directory File Counts per file system TopDSpc=20 # Number of Largest Directory Space used per file system TopBigFile=20 # Number of Largest Files per file system MinFSz=50000000 # Minimum File System Size (in bytes) MinFCnt=100 # Minimum Directory File Count MinDSpc=10000 # Minimum Directory Space (in Kbytes) # # include_dir_scans="F" # set to "T" to turn on directory scans, see below! # ------------------------------------------------------------------ On systems with an uncommonly large number of files/directories or slower disk reads/performance this can take a while with the Disk File Counts and Directory File Space enabled. It should be tested manually before turning on the (Disk File Counts) and (Directory File Space) in each directory. By default, these two are not incorporated, but may be turned on manually with "pnadcp.sh -a" or modify the variable in pnadcp.config (include_dir_scans="T") ------------------------------------------------------------------ include_dir_scans="F" pnedcp.config options Power Navigator’s External Data Collection Process currently issues a PS com-mand every interval and stores the result in a file called mpgdata3.hostname. Only the processes that consume more than the thresholds percentages below will be saved. export percent_mem=1 export percent_cpu=1 export vsz_threshold=30000


Power Navigator Host Code Customization Transfer_xx.config

The Transfer_xx.config file is used to configure Power Navigator to transfer all the required files from each server to a central location. Four examples of these transfer_xx.config files are included in the mpgpn.tar file. The four examples are for ftp, scp, rcp, and cp. Just substitute the xx with the desired method and extract from mpgpn.tar and configure. Parameter examples from the transfer_cp.config file is below: transfer_method (ftp,scp,rcp,cp) transfer_method="cp" transfer_target_dir (Note: Directory must exist, and user must have rights) transfer_target_dir="/opt/mpgsamba/mpg_servers_data" transfer_options transfer_options="-p" datafile datafile="mpgdata2.AIX720" datafile_admin datafile_admin="mpgdata4.AIX720" datafile_external datafile_external="mpgdata3.AIX720" current data data_current="mpgdata2_current.AIX720" rackfile rackfile="rackdata.AIX720" permissions of files to be transferred (recommend 640 or 644) permsfiles="644"
