Creates a PDF report out of sar files
Written originally by Ray, I cleaned it up to make it more user-friendly, use less memory and make it multi-processor capable.
Here you can see how such a pdf looks like: http://acksyn.org/software/sarstats/sar19.pdf And a more complex example (~60MB): http://acksyn.org/software/sarstats/sar01.pdf
The following creates a report off 'sar01' and adds a graph with three datasets (udpsck, rawsck,tcp-tw):
./sarstats --out sar01.pdf --custom 'foo:udpsck,rawsck,tcp-tw' /var/log/sa/sar01
To list the names of all the possible graphs just run:
./sarstats --list /var/log/sa/sar01
To export a single custom graph in svg format run:
./sarstats --output base --svg 'ldavg-1,ldavg-5,ldavg-15' \
--label 'peak:2014-02-17 14:30:00' demo/var/log/sa/
This will produce the following output:
It is also possible to print a single graph in ascii format:
./sarstats --ascii 'tcp/s' tests/sar-files/1/sar19
tcp/s - tests/sar-files/1/sar19

Q: Why don't you use 'sadf' instead of doing all that parsing?
-
A: sadf does not parse 'older' SA files. So no RHEL 5 and even RHEL 6 files cannot be parsed on a current (F20) Fedora box.
-
Q: I found a bug, where do I report it?
-
A: Drop me an email or open an issue in github
-
Q: Shouldn't you move to PCP or something more capable anyway?
-
A: Yes, as soon as PCP is more widespread
-
Q: In network graphs with bonding the bond interface is never shown?
-
A: Because, depending on the bonding mode, the underlying ethX interface has the exact same traffic patterns and is drawn afterwards
-
Q: When using --maxgraphs 15 on a big sar file (one with many scsi devices for example) I get a traceback with IOError: Cannot open resource "...."
-
A: You are hitting the file number limit due to the many images that are being opened. Increase the limit per user (https://rtcamp.com/tutorials/linux/increase-open-files-limit/)
