How to parse bhist log - awk

Question

I am using IBM LSF and trying to get usage statistics during a certain period. I found that bhist does the job, but the short form bhist output does not show all of the fields I need.
What I want to know is:
Is bhist's output field customizable? The fields I need are:
<jobid>
<user>
<queue>
<job_name>
<project_name>
<job_description>
<submission_time>
<pending_time>
<run_time>
If 1 is not possible, the long form (bhist -l) output shows everything I need, but the format is hard to manipulate. I've pasted an example of the format below.
For example, the number of line between records is not fixed, and the word wrap in each event may break the line in the middle of a word I'm trying to scan for. How do I parse this format with sed and awk?

Answer 1

I'm adding a second answer because it might help you with your problem without actually having to write your own solution (depending on the usage statistics you're after).
LSF already has a utility called bacct that computes and prints out various usage statistics about historical LSF jobs filtered by various criteria.
For example, to get summary usage statistics about jobs that were dispatched/completed/submitted between time0 and time1, you can use (respectively):
bacct -D time0,time1
bacct -C time0,time1
bacct -S time0,time1
Statistics about jobs submitted by a particular user:
bacct -u <username>
Statistics about jobs submitted to a particular queue:
bacct -q <queuename>
These options can be combined as well, so for example if you wanted statistics about jobs that were submitted and completed within a particular time window for a particular project, you can use:
bacct -S time0,time1 -C time0,time1 -P <projectname>
The output provides some summary information about all jobs that match the provided criteria like so:
$ bacct -u bobbafett -q normal
Accounting information about jobs that are:
- submitted by users bobbafett,
- accounted on all projects.
- completed normally or exited
- executed on all hosts.
- submitted to queues normal,
- accounted on all service classes.

This command also has a long form output that provides some bhist -l-like information about each job that might be a bit easier to parse (although still not all that easy):
$ bacct -l -u bobbafett -q normal
Accounting information about jobs that are:
- submitted by users bobbafett,
- accounted on all projects.
- completed normally or exited
- executed on all hosts.
- submitted to queues normal,
- accounted on all service classes.

Answer 2

Long form output is pretty hard to parse. I know bjobs has an option for unformatted output (-UF) in older LSF versions which makes it a bit easier, and the most recent version of LSF allows you to customize which columns get printed in short form output with -o.
Unfortunately, neither of these options are available with bhist. The only real possibilities for historical information are:
Figure out some way to parse bhist -l -- impractical and maybe not even possible due to inconsistent formatting as you've discovered.
Write a C program to do what you want using the LSF API, which exposes the functions that bhist itself uses to parse the lsb.events file. This is the file that stores all the historical information about the LSF cluster, and is what bhist reads to generate its ouptut.
If C is not an option for you, then you could try writing a script to parse the lsb.events file directly -- the format is documented in the configuration reference. This is hard, but not impossible. Here is the relevant document for LSF 9.1.3.
My personal recommendation would be #2 -- the function you're looking for is lsb_geteventrec(). You'd basically read each line in lsb.events one at a time and pull out the information you need.
