cat file1 file2 file3 > concatenated-file). This feature does not apply to vmstat and iostat files that provide only time and not date: in this case concatenate the files by yourself in the right order and load the result (e.g. There is no requirement on file names since pGraph will use time stamps inside the files to correctly merge data. pGraph is capable of automatically merge the content of files and treat them as a single input stream: just put all files in the same directory and load them with the single host, multiple files option. The same performance tool can be run several times (for example, an nmon running every day for 24 hours) on the same operating system and the administrator may need to study all the outputs.

When the file is completely loaded, a set of graphs are made available, depending on the file content (for example, iostat does not provide CPU data). When a single file is selected, pGraph automatically detects its type and parses it.

you can mix the previous cases and perform additional operations on data.

If you want pGraph to provide an estimate of real process consumption (as if the technology could provide a capability similar to the one available on IBM PowerVM), add a single line at the beginning of the file with the syntax "cores = number_of_cores. NOTE When using sar on Solaris or HP-UX no information is provided about the number of available cores. HMC's data collection using "lslparutil" command Topasout (any source, for example xmwlm, topas_cec) The following table shows the current tools supported: Command PGraph can be easily adapted to read the output of many performance tools, provided they print a time stamp for each data sample. There is no limit in file size or in the number of samples present in the data. pGraph will automatically detect the file format and load the data. In order to save disk space, it is possible to compress the text file in GZIP format with a ".gz" extension. Just save the text output of the tool on a file with the name you prefer. PGraph can read data from several performance tools. See also HMC Scanner page from the same author. It a personal project of the author, Federico Vagnini (IBM Italy). No guarantee is given or implied, and you cannot obtain help from IBM. This tool is not officially supported by IBM.

PGraph is packaged in a single Java jar file available in the download section of this page. If you have any problem or any suggestion to improve pGraph, please send me a mail ( Since new features are mostly suggested by users, propose yours! The tool is constantly updated to match changes in tool syntax, to manage new data types and to add new features.

graphs can be exported in PNG or CSV format.

zoom feature to show data related to a user defined time period.

complex mixing of data is possible (e.g.

load of files belonging to multiple operating systems to show global processor usage.

automatic merge of data files belonging to same operating system.

data file can be in GZIP format (highly recommended to save space).multiple operating systems (AIX, Linux, Solaris, HP-UX).support for multiple data formats (nmon, vmstat, topasout, iostat, lslparutil, sar).

There is no limit on input data size and user can view graphs related to the entire timeframe or can select a specific time period. PGraph is a Java program designed to read multiple performance data formats and to produce graphs either interactively or in batch mode.
