Description: Provides SNMPv2 management objects for Computer Associates (CA) network management platform integration.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is CA-SNMP-MIB8?

CA-SNMP-MIB8 is a private enterprise MIB from Computer Associates (CA) that instruments a reverse-proxy/caching HTTP service for integration with CA's Unicenter network management platform. It exposes counters for HTTP request types (GET, HEAD, POST, PURGE), cache hit/status statistics, connection counts to clients and servers, and HTTPS and regex-matched request traffic. Administrators use it to monitor the health and load of the caching software: request throughput, established connection counts, and cache effectiveness together indicate whether the proxy is servicing traffic normally or is overloaded or misconfigured. It defines its own trap object (caTraps) for asynchronous fault/event notification rather than relying on a separate standard MIB. It is typically deployed on CA-managed reverse-proxy or web-caching servers within a broader Unicenter-monitored enterprise network, and administrators can download the CA-SNMP-MIB8 file to integrate it with their monitoring tools.

IPNetwork Monitor allows you to monitor SNMP objects defined in CA-SNMP-MIB8. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

  • Array Networks web-caching/application delivery controller appliances (legacy)

Monitoring Examples

An operator would poll requestsReceived, getRequests, postRequests, and purgeRequests alongside cacheBasicStats and cacheStatus to see the current request mix and cache efficiency of the revProxyCache. A sudden rise in requestsToHttps combined with growing serverEstabConn but flat clientEstabConn could reveal that backend server connections are being exhausted while client demand keeps rising. Comparing requestsOnRegex and requestsToUrl over time helps confirm whether specific URL patterns are driving unusual load.

What Can Be Monitored

  • HTTP request rate by method
  • cache hit/status
  • client and server established connections
  • HTTPS request volume
  • URL/regex-matched request counts

How to Use in IPNetwork Monitor

Example using requestsReceived OID:

Select an Array Networks web-caching/ADC appliance (legacy) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type requestsReceived into the Find box to locate it in the OID tree, then select it and click OK. It reports the total number of requests received by the reverse proxy cache. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
