Monitoring NIC Proxies on Solaris Platforms

You can use MBeans to monitor NIC proxies. MBeans are a feature of the Java Management Extension (JMX) software. If you want to monitor the MBeans for NIC proxies, your Web application server must include a JMX agent.

NIC proxies create one instance of an MBean called NicProxyMgmt to provide information about the role of the NIC proxy to the JMX agent. The way you view the MBeans depends on the particular Web application server and the interfaces that its JMX agent provides. Table 15 shows the information that this MBean provides.

You can reset the values of many NicProxyMgmt MBean properties to zero.

To reset the NicProxyMgmt MBean properties to zero:

Table 15 shows which counters the reset operation affects.

Ability to Reset to Zero

nicProxyName

Name of the NIC proxy. Different NIC proxies may exist, providing different functionality.

No

numKeysCachedLocally

Number of key-value pairs that are cached in the NIC proxy (the bigger the cache, the less likely the NIC proxy will have to involve the distributed NIC components in lookups across the network).

No

numLookups

Number of times that the Web application containing this NIC proxy has requested the NIC proxy to look up a data key.

Yes

numLookupErrors

Number of lookups that have failed.

Yes

numKeysNoMatch

Number of lookups in which the provided key does not map to any value.

Yes

numKeysOneMatch

Number of lookups in which the provided key maps to exactly one value.

Yes

numKeysMultiMatch

Number of lookups in which the provided key maps to more than one value.

Yes

lookupTimeAvg

For the 100 most recent (successful and unsuccessful) lookups, the average time (in milliseconds) of the lookup.

Yes

lookupTimeMin

For the 100 most recent (successful and unsuccessful) lookups, the minimum time (in milliseconds) of the lookup.

Yes

lookupTimeMax

For the 100 most recent (successful and unsuccessful) lookups, the maximum time (in milliseconds) of the lookup.
