10 Troubleshooting System Reporter
Troubleshooting Overview
The first step when troubleshooting System Reporter is to identify the component that is causing
problems (see
Figure 2 (page 26) for the structure of System Reporter).
•
If there are problems in sampling components see “Troubleshooting the Sampling Components”
(page 217) . Examples of the types of problems encountered include:
•
The sampler service or daemon stops.
•
The sampler fails to sample data from a particular HP 3PAR StoreServ Storage.
•
If there are problems with the Adaptive Optimization components, see “Troubleshooting
Adaptive Optimization Components” (page 219) .
•
If there are problems generating interactive reports in a web browser see “Troubleshooting
the Web Server Components” (page 219) .
•
If there are problems using the Excel client, see “Troubleshooting the Excel Client” (page 219) .
Some problems generating reports in the Excel client may be associated with the web server
components as well.
•
If there are problems with the database server, see “Extracting Data from the Database with
sysbck ” (page 220) or “Dumping the Entire Database” (page 224) .
Troubleshooting the Sampling Components
The System Reporter sampling components include several processes. Most of these processes
create log files that are the first things you should look at when troubleshooting.
Sampling Component Log Files
In general, a sampling component process named <process_name> creates a log file named
<process_name>.log
. However, for some processes a separate instance of the process is
created for each HP 3PAR StoreServ Storage and for these processes the log file is named
<process_name>_<inserv_ip>.log
where <inserv_ip> is the IP name or address of the
system. On Windows, this is in the HP 3PAR System Reporter directory (default location for
the directory is C:\Program Files\3par\System Reporter\log). On Linux, the log file is
in the /var/log/sampleloop/ directory.
NOTE: The <process_name> excludes the executable file name extensions .exe (Windows)
or .bin (Linux).
For example, the main process (sampleloop) runs as a service on Windows or as a daemon on
Linux and it creates a log file called sampleloop.log. As shown in
Figure 2 (page 26) , the
sampleloop process creates an inservsample process for each HP 3PAR StoreServ Storage and
these processes create log files such as inservsample_192.168.1.19.log.
At the beginning of each day (or whenever a process is restarted), a new <process_name>.log
is created and the old logs are rolled to <process_name>.<x>.log, where <x>is 1, 2 3 or 4.
When log files are rolled, the previous <process_name>.4.log file is deleted and replaced
with the <process_name>.3.log file.
When reporting a problem with sampling, please provide the entire log directory.
CAUTION: If you get an error in a sampling component that causes the service or daemon to
stop, save the entire log directory before restarting the service or daemon so that you do not lose
the error information in the logs.
