FYI – If you use the amqsact sample program for Activity Tracing, there is a bug in how the -s (startTime) and -e (endTime) switches work to only find records for a given time range. There is a bug in both the start and end time check.
The amqsact logic has the following to build one of the tm structures that is used for the check.
| Code: |
sscanf(MsgStartTime, "%2u.%2u.%2u",
&(startTm.tm_hour),
&(startTm.tm_min),
&(startTm.tm_sec));
|
However, MsgStartTime has a format like “13:11:01”. This causes some of these fields in the tm structure to not get parsed correctly, and therefore the time selection does not work correctly.
The amqsact code needs to be changed to the following to work correctly for the time selection:
| Code: |
sscanf(MsgStartTime, "%2u:%2u:%2u",
&(startTm.tm_hour),
&(startTm.tm_min),
&(startTm.tm_sec));
.
.
sscanf(MsgEndTime, "%2u:%2u:%2u",
&(endTm.tm_hour),
&(endTm.tm_min),
&(endTm.tm_sec));
|
The format of how amqsact reads in the -s and -e is a little odd (i.e. 2017-07-07 11.15.00), but not a bug:
| Code: |
sscanf(pval, "%4u-%2u-%2u %2u.%2u.%2u",
&(startTime.tm_year),
&(startTime.tm_mon),
&(startTime.tm_mday),
&(startTime.tm_hour),
&(startTime.tm_min),
&(startTime.tm_sec));
|
For my own custom version of amqsact that I use, I changed it to the following (i.e. 2017-07-02T11:15:00)
| Code: |
sscanf(pval, "%4u-%2u-%2uT%2u:%2u:%2u",
&(startTime.tm_year),
&(startTime.tm_mon),
&(startTime.tm_mday),
&(startTime.tm_hour),
&(startTime.tm_min),
&(startTime.tm_sec));
|
I am not sure how this time selection part of the amqsact sample was tested successfully, as it mostly just does not work with the current bug.
