Chapter 11 Troubleshooting the Statistics Infrastructure
Diagnosing Problems with Statistics Values
Errors When Retrieving Data from the Statistics Manager EDM
You need to determine whether requests from the show command or other management agents are being
received and correctly interpreted by the statistics manager. Table 11-8 lists the debug commands that
must be enabled while running the show command.
Additionally, examining the diagnostic output from the show statsd manager info command before and
after the request shows whether or not the request is being received by the statistics manager EDM.
Timeouts and Delays When Retrieving Data
Table 11-9 lists the show and debug commands that help you identify the client that is not responding.
Table 11-8 Debug Commands for the Statistics Manager
Command Description
debug statsd manager errors Displays the errors for the statistics manager.
debug statsd manager sysdb-edm Displays the EDM-related activity of the statistics manager.
Table 11-9 show Commands for Statistics Requests
Command Description
show process blocked location all Displays the statistics manager or any statistics collector
process that is being blocked.
show process statsd manager Displays whether all threads are in receive state (the expected
state).
show statsd requests Displays the details of the recent requests, including the list of
collectors that responded successfully.
show statsd collectors brief Displays the entries for collectors on all nodes. If entries are
missing for any node, this indicates a problem with the GSP
group on that node.
show statsd manager info Displays the request module information that shows whether
any requests have failed or timed out.
show statsd manager trace reverse Displays the latest traces first. You should locate lines such as
“Stats request 1 completed with 0/7 responses outstanding.”
For each request, you must also look at each response that was
received, such as “Received response with 1 element(s) for
request 3 from member with node ID 0x0, pid 217201.” or
"Received NACK with 0 element(s) for request 3 from
member with node ID 0x0, pid 229528".
If there is only one response outstanding, the problem resides
with the collector that did not reply ( as it is blocked, or failed
to join the group). Whereas, if there are many missing
responses, the problem lies with the statistics GPS group,
which is broken on one or more nodes.
