There are several initial steps that you can take to troubleshoot AMP performance problems, including slow page
loads and timeout errors. Initial troubleshooting steps would include the following:
 Increasing the polling period settings on the Groups > Basic page.
 Increasing the polling period time for groups with routers and switches.
 Adding additional memory to the server. Please consult the sizing information in the latest edition of the Dell
PowerConnect W-AirWave Server Sizing Guide at support.dell.com/manuals
or contact Dell support at

Database Statistics
Top 5 Tables (by row count) The five largest tables in AMP. Degraded performance has been noticed for in some cases for
tables over 200,000 rows. Decreasing the length of time client data is stored on the AMP page is
recommended if a user/client table exceeds 250,000 rows.
Database Table Scans The number of database table scans performed by the database.
Database Row Activity The number of insertions, deletions and updates performed to the database.
Database Transaction
Activity
The number of commits and rollbacks performed by the database.
Disk Space
Disk Space Pie charts that display the amount of used and free hard drive space for each partition. If a drive
reaches over 80% full, you may want to lower the Historical Data Retention settings on the AMP
Setup > General page or consider additional drive space.
