Traverse: How to detect a crashed database table

To create a test in Traverse to detect a crashed MySQL database table on a BVE or DGE:

  • Navigate to 'Administration -> Devices' .  If logged into Traverse as a 'superuser' or member of an Admin Group, then select the department where the Traverse server is provisioned.
  • Select the 'Tests' link for the Traverse server (either a combined BVE/DGE or a DGE only)
  • Select 'Create New Standard Tests'
  • Select 'Create new tests by selecting specific monitors', check the box for the 'sql_value' monitor, select 'Add Tests'
  • Choose the Test Category 'SQL Query Result (MySQL)' to highlight it, then select 'Continue'
  • Check the box to the left of 'SQL Query Result (MySQL)'
  • Change enter the following values:
    • Port: 7663
    • User Name: emerald
    • Password: mysql
    • Password (again): 
    • Database: aggregateddatadb
    • Query: select count(*) from (select checksum, table_comment from information_schema.tables) as tb where table_comment like '%crashed%';
    • As Test Value Rises, Severity: Ascends
    • Thresholds warn: 1
    • Thresholds critical: 1
  • Do not change the value for the 'JDBC Driver'
  • Ensure that the box to the left of 'SQL Query Result (MySQL)' is checked, then select 'Provision Selected Tests'
  • Select the 'modify' icon (orange circle with embedded arrow) for the test 'SQL Query Result (MySQL)'
  • Change the Test Name to 'Number of Data tables crashed tables' then select 'Submit'

Allow a few minutes for the new test be scheduled and the result updated.  The result reflects the number of crashed tables detected within the specified database and will either be 'Ok' (zero) or 'Critical' (value greater than zero).

Similar additional tests may be added for a Traverse BVE using the previous steps and substituting the values from the table below:

Test Name Database Applicable Server
LiveEvents Tables Crashed liveeventsdb BVE
Summary Tables Crashed summarydb BVE
Process Tables Crashed processdb DGE
Scheduler Tables Crashed schedulerdb BVE
SLA Tables Crashed sladb BVE
