TrueSight 10.x: How to increase Query Agent Window's buffer size?

Sam Truong Oct 13, 2017 11:17 AM

Hi All,

Does anyone know how to increase the buffer size of the TS' Query Agent window?

I have a customer who doesn't have access to their Patrol Agents and they have to do everything via this window. For example, say I need to retrieve the content of a log file:

print(system("cat $PATROL_HOME/log/mylog.txt"));

print(system("tail -n 5000 $PATROL_HOME/log/mylog.txt"));

But if the mylog.txt file is too large, the 1st query will not return anything.

Does this ring a bell with anyone? If yes, any idea/suggestion would be more than welcome.

Thanks and have a nice weekend!

Sam.

Hi, Sam!

Could you show me output for this command:
print(grep("is bigger than the maximum",cat(get("agentLogPath")), "i"));

Hi Oleg,

Small log file:
print(system("type %patrol_home%\\log\\SEN_CMPL_debug_km_3181_2017-10-12-14-53.log"));

• DEBUG: 2017-10-12 14:53:03: [SEN_CMPL_MAIN]: Creating /SEN_CMPL_MAIN/CMPL
DEBUG: 2017-10-12 14:53:04: [SEN_CMPL_MAIN]:

Same file with your command:
Command :    print(grep("is bigger than the maximum",cat(get("%PATROL_HOME%\\log\\SEN_CMPL_debug_km_3181_2017-10-12-14-53.log")), "i"));
Results :

Executed successfully on the PATROL agent.

Bigger log file, about 25MB:
Command :    print(system("type %patrol_home%\\log\\SEN_CMPL_debug_java_3181_compel-em-2014_2017-10-12-15-28.log"));
Results :

Executed successfully on the PATROL agent.

Results :

Executed successfully on the PATROL agent.

Thanks,

Hi Sam Truong ,

Try this PSL (replacing the log file):

chan = fopen("C:\\Program Files\\BMC Software\\Patrol3\\log\\SEN_MS_debug_km_3181_2017-10-18-23-46.log", "r"); if(chan) { data = read(chan, 1048576); while(errno != 55) { print(data); data = read(chan, 1048576); }} else { print("file not found\n"); }

This will read 1MB chunks of data and print it to SOW.

Dear All,

I tried below PSL for Windows Server Agent but it is giving error. Can anyone please give correct PSL scrip to check dir and read log files for Windows server Agent using Query Agent Option.

As below PSL command for Linux Agent is working fine.
print(system("ls -l %PATROL_HOME%/log/"));

So Please suggest for Windows. I am new to PSL scripting.

Thanks,
Ashroba

Hi Oleg,

PF output of above query which is executed successfully.

Can you please send me any basic recommended document/Links for PSL scripting at ujgare.ash93@yahoo.com. I will go through it to learn PSL.

Thanks,
Ashroba
