System Reporter Error

Recently I had some problems with System Reporter, the symptoms were that when I went to run a report it showed no data available for the period. When I checked the System Reporter server I saw that the 3Par system reporter sampler service had stopped. To see what the issue was I checked in the Sampleloop log located in the following location C:Program Files (x86)3PARSystem, towards the end of the log I saw the following error:

2014-07-21 08:51:33: MySQL DB error executing show full columns from statldrg_hourly_2: mysqlsel/db server: Table ‘.inservstatsstatldrg_hourly_2’ is marked as crashed and should be repaired

In order to repair the MySQL tables I took the following steps:

 

1.   Stop in this order the following services: System Reporter service, Apache service and MySQL Server service from services.msc

2.  Open the Task Manager and select show process from all users. If the following processes exist end them: inserv_perf.exe, Trimdb.exe, Compactdb.exe, inservsample.exe

3.     Before you start make a backup of the current database. The default location for the DB is C:ProgramDataMySQLMySQL Server 5.5datainservstats. You can back this up by just making a copy of the folder

4.     Open command prompt as an administrator and change directory to where MySQL database is located e.g. C:ProgramDataMySQLMySQL Server 5.5datainservstats

5.     The command below will repair and re index the tables just copy and paste it into your command prompt. You will need to replace the X with the version of MySql you are using eg 5.5

“C:Program FilesMySQLMySQL Server 5.Xbinmyisamchk.exe” -r –key_buffer_size=512M –sort_buffer_size=512M –read_buffer_size=8M –write_buffer_size=8M *.MYI

Wait for this command to complete, it can take some time, you will know it’s done when it goes back to the command prompt.

5.     Start the MySQL Server service, System Reporter service and Apache service.

In my case it took a good hour to run and then System Reporter was back from the dead, good times
