NAME
pbs_snapshot - Linux only. Capture PBS data to be used for diagnostics
SYNOPSIS
pbs_snapshot -o <output directory path> [-H <server host>]
[-l <log level>] [--accounting-logs=<number of days>]
[--additional-hosts=<hostname list>]
[--daemon-logs=<number of days>] [--map=<file path>]
[--obfuscate]
pbs_snapshot --version
DESCRIPTION
You use pbs_snapshot to capture PBS data for diagnostics. This tool is
written in Python and uses PTL libraries, including PBSSnapUtils, to
extract the data. You can optionally anonymize the PBS data.
Required Privilege
To run pbs_snapshot , you must be root on Linux or Admin on Windows.
OPTIONS
-H <server host>
Specifies server hostname. By default, pbs_snapshot uses the
value of the PBS_SERVER parameter in pbs.conf. When you use this
option, pbs_snapshot uses server host instead.
-l <log level>
Specifies level at which pbs_snapshot writes its log. The log
file is pbs_snapshot.log, in the output directory path specified
using the -o <output directory path> option.
Valid values, from most comprehensive to least: DEBUG2, DEBUG,
INFOCLI2, INFOCLI, INFO, WARNING, ERROR, FATAL
Default: INFOCLI2
--accounting-logs=<number of days>
Specifies number of days of accounting logs to be collected; this
count includes the current day.
Value of number of days must be >=0:
If number of days is 0, no logs are captured.
If number of days is 1, only the logs for the current day
are captured.
Default: pbs_snapshot collects 30 days of accounting logs
--additional-hosts=<hostname list>
Specifies that pbs_snapshot should gather data from the specified
list of non-server hosts. pbs_snapshot always gathers data from
the server host.
The command collects the following information from the specified
hosts:
MoM and comm logs, for the number of days of logs being
captured, specified via the --daemon-logs=<number of days>
option
The PBS_HOME/mom_priv directory
System information
Format for hostname list is a comma-separated list of one or more
hostnames:
<hostname>[, <hostname> ...]
This option can greatly bloat the size of the snapshot, and cause
pbs_snapshot to take a long time copying what may be large amounts
of data over the network.
--daemon-logs=<number of days>
Specifies number of days of daemon logs to be collected; this
count includes the current day. All daemon logs are captured on
the server host, and if you specify --additional-hosts=<hostname
list>, MoM logs are captured on those hosts as well.
Value of number of days must be >=0:
If number of days is 0, no logs are captured.
If number of days is 1, only the logs for the current day
are captured.
Default: pbs_snapshot collects 5 days of daemon logs
--map=<file path>
Specifies path for file containing obfuscation map, which is a
<key>:<value> pair-mapping of obfuscated data. Path can be abso-
lute or relative to current working directory.
Default: pbs_snapshot writes its obfuscation map in a file called
obfuscate.map in the location specified via the -o <output direc-
tory path> option.
Can only be used with the --obfuscate option.
--obfuscate
Obfuscates (anonymizes) or deletes sensitive PBS data captured by
pbs_snapshot.
Obfuscates the following data:
euser, egroup, project, Account_Name, operators, managers,
group_list, Mail_Users, User_List, server_host, acl_groups,
acl_users, acl_resv_groups, acl_resv_users, sched_host,
acl_resv_hosts, acl_hosts, Job_Owner, exec_host, Host, Mom,
resources_available.host, resources_available.vnode
Deletes the following data:
Variable_List, Error_Path, Output_Path, mail_from, Mail_Points,
Job_Name, jobdir, Submit_arguments, Shell_Path_List
--version
The pbs_snapshot command returns its PBS version information and
exits. This option can only be used alone.
Arguments to pbs_snapshot
-o <output directory path>
Path to directory where pbs_snapshot writes its output tarball.
Required. Path can be absolute or relative to current working
directory.
For example, if you specify -o /temp, pbs_snapshot writes
"/temp/snapshot_<timestamp>.tgz".
The output directory path must already exist.
Output
Output Location
You must use the -o <output directory path> option to specify the
directory where pbs_snapshot writes its output. The path can be abso-
lute or relative to current working directory. The output directory
must already exist. As an example, if you specify "-o /temp",
pbs_snapshot writes "/temp/snapshot_<timestamp>.tgz".
