For adding syslog support in PTL we will have to make changes in two files- pbs_logutils.py and pbs_testlib.py.
New added functions to read from syslog will be added to the existing class PBSLogUtils()
———————In pbs_logutils.py——————
Class PBSLogUtils(object):
facility = //PBS_SYSLOG from pbs.conf
severity = // PBS_SYSLOGSEVR from pbs.conf (by default NONE)
Methods:
def _get_log_type()
Summary: logic for which messages to read (local logs / syslog)
Description:
1) read from PBS.conf - PBS_SYSLOG & PBS_LOCALLOG.
2) Logic for whether to read local logs/ syslog we will follow this table -
...
PBS_SYSLOG | PBS_LOCALLOG | Which log to check in log_match() |
0 | 0 | Throw error |
0 | 1 | Local_log |
set (1-7) | 0 | Syslog |
set (1-7) | 1 | Match in both logs |
| unset | unset | Local_log |
Note: In row 4 where we have to match in both syslog and local log, we would have to call _log_match() twice.
Note: In case of row 4 the return value for log_match() will return lines from local_logs only.
Note: Currently we are only supporting for the current syslog file and not for previous days file. That would be covered in PP-969
Note: The error thrown will be PtlLogMatchError
Return:
self.file_to_check (/ / file_to_check =1 for syslog, file_to_check=2 for local logs and file_to_check=3 for both)
New methods:
def _get_syslog_lines(hostname, n, logval):
...
class PBSService(PBSObject)
New method
def _get_log_type()
Summary: logic for which messages to read (local logs / syslog)
Description:
1) read from PBS.conf - PBS_SYSLOG & PBS_LOCALLOG.

Description:
1) PBSLogUtilsself._get_log_type() to check if local logs/ syslog is to be checked
x= PBSLogUtils._get_log_type(syslog=syslog)
2) if x =1 or 3 - read _log_match(syslog=true)
