MONITORING B-SERIES SWITCHES
Use pathinfo, topologyshow or urouteshow to visualize the fabric
Use porterrshow and portstatsshow to see if there are any port errors / discarded frames.
Note: These are just counters so you would need a set of logs, duplicate the problem and then
capture a second set of logs to determine if the errors are incrementing at the time the problem
was happening
Use portperfshow / APM to see the I/O (must be captured during the time of the problem). If the
switch has APM Web Tools, Fabric Manager or CLI can be used to capture end-to-end
performance data
Fabric Watch can be used to set thresholds to see ISL hot spots and send SNMP alerts. What also
makes this tool useful is it can be used to constantly monitor the fabric
SAN Health can be also be used to look for hot spots and I/O over time; it also tells you if you have
a zoning configuration enabled
MONITORING M-SERIES SWITCHES
SAN Routing: EOSdc -> RTM_Flow_01 file can be used to draw out the fabric
Port Statistics log can be used to look at port errors / discarded frames. As with the B-Series
switches these are just counters so a before and after set of logs would be required to determine is
the error counters are increasing. LIN log can be looked at for link/port issues
Performance reports (using EFCM Standard or EFCM Enterprise can be run to look at I/O rates on
ports.
Thresholds can be set to determine ISL hot spots
BB Credits: EOSdc -> PortModules files can be used to look at BB-Credit counters. Note: M-i10K
only: When Remote Fabric license is enabled, a 1 Gbit/sec, 2 Gbit/sec or 10 Gbit/sec port can be
configured from 1 to 1373 BB_Credits
