Description: Manages health monitoring probes and real server availability tracking for Cisco Server Load Balancing platforms.

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 CISCO-SLB-HEALTH-MON-MIB?

CISCO-SLB-HEALTH-MON-MIB extends CISCO-SLB-EXT-MIB to define health-monitoring probes for Cisco Server Load Balancing (SLB) devices, which distribute incoming packets/connections across a farm of real servers, firewalls, or caches. It belongs to the load-balancing/high-availability technology area and exposes probe configuration data: probe type, interval, retry count, failed-interval, receive/TCP-open timeouts, and alternate destination or DNS-domain targets used by the probe. Its monitoring purpose is to continuously verify the software/service reachability of each real server behind the load balancer — a probe repeatedly timing out or failing indicates that server or service instance is unhealthy and should be pulled from rotation, which is core to preventing traffic from being sent to a dead backend. It is an extension of, and dependent on, CISCO-SLB-EXT-MIB for the underlying server-farm and real-server object model. It is typically deployed on Cisco SLB-capable switches/appliances (e.g. Catalyst with CSM, or ACE modules) front-ending server farms in data centers. Engineers can download the CISCO-SLB-HEALTH-MON-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-SLB-HEALTH-MON-MIB. 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

Cisco Server Load Balancing switch/module (e.g. CSM/ACE)

Monitoring Examples

An operator would poll cslbxProbeCfgTable's cslbxProbeType, cslbxProbeInterval, and cslbxProbeRetries per cslbxProbeName to confirm a health probe (e.g. TCP or DNS-based) is configured to run frequently enough to catch outages quickly. If cslbxProbeFailedInterval and cslbxProbeReceiveTimeout or cslbxProbeTcpOpenTimeout values are being exceeded repeatedly for a given probe tied to cshMonSfarmProbes, that signals the associated real server is failing health checks and the SLB device should have already taken it out of the active server farm.

What Can Be Monitored

probe type and interval
probe retry/failure thresholds
receive and TCP-open timeouts
real server health/probe status

How to Use in IPNetwork Monitor

Example using cshMonProbeTotalSentProbes OID:

Select a Cisco Server Load Balancing switch/module (CSM/ACE) 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 cshMonProbeTotalSentProbes into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. This object identifies the number of probes sent to the real servers. 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.

ciscoSlbHealthMonMIB	1.3.6.1.4.1.9.9.508			An extension to the CISCO-SLB-EXT-MIB for SLB health monitoring probes. SLB: Server Load Balancing. Server load balancing provides for the balancing of packets and connections arriving at the SLB device across a number of other devices, such as real servers, firewalls, or caches. A system containing an SLB device typically exhibits higher performance, scalability, and reliability than any of the devices being load balanced. An SLB device determines how to handle incoming frames and connections according to the contents of incoming data and various configuration options. In determining how to handle incoming data, an SLB device may examine the data at any OSI layer, including Layer 7. This MIB includes information on the health monitoring probes that can be used for monitoring the health of real servers. Health checking provides the ability of the content switch to detect if a server is available for load balancing. Health probes used for health checking allow testing various application level functionality. The active probes are sent at regular intervals and the lack of a response can lead to a specific server or and entire group of servers being declared as not available. Following probes are based on TCP: http, https, smtp, telnet, ftp, tcp, script, ldap, tacacs, sip, echo, finger. Following probes are based on UDP: tftp, udp, sip, echo,. Acronyms and terms: SLB Server Load Balancing VIP Virtual Server IP address NAT Network Address Translation SF Serverfarm FT Fault Tolerance SSL Secure Sockets Layer TLS Transport Layer Security Server Farm : Contains cluster of Real Server Real Server : Real Servers are physical devices assigned to a server farm. Real servers provide services that are load balanced. Health Probe : The mechanisms to monitor the health of real servers or rservers. Virtual IP : The IP through which the real server is reached during load balancing. Probe Instance : An instance of the probe identified by cslbxProbeName. A probe instance is created for every probe association. For example: When a probe is associated with a real server a probe instance is created for that probe. Probe Port : This mechanism introduces the capability Inheritance for the probe instance to inherit the virtual ip address port or the the real server port (identified by cshMonServerfarmRealServerPort) when the probe port (identified by cslbxProbePort) is not configured. The precedence of inheritance is as follows 1. Probe's configured port 2. Real server port 3. Virtual ip address port 4. Probes default port identified by cslbxProbePort. Examples: Scenario 1: Probe's configured port = 100 Real server port = 200 Virtual ip address port = 300 Probe's default port = 80 Inherited port of the probe instance = 100 Scenario 2: Probe's configured port = not configured Real server port = 200 Virtual ip address port = 300 Probe's default port = 80 Inherited port of the probe instance = 200 Scenario 3: Probe's configured port = not configured Real server port = not configured Virtual ip address port = 300 Probe's default port = 80 Inherited port of the probe instance = 300 Scenario 4: Probe's configured port = not configured Real server port = not configured Virtual ip address port = not configured Probe's default port = 80 Inherited port of the probe instance = 80 Scenario 5: There can be scenarios wherein there may be multiple inherited ports for a probe instance. There are configurations where multiple virtual ip addresses with different ports share the same probe instance and the probe has no configured port or real server port attached. In that case the shared probe instance has multiple inherited ports. A typical scenario might be Probe's configured port = not configured Real server port = not configured Ports of the virtual ip addresses which shares the probe instance = 300,400 Probe's default port = 80 Inherited port of the probe instance = 300,400
