Description: Monitors environmental sensors and dry contact inputs on HW group Damocles I/O monitoring units.

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 DAMOCLES-MIB?

DAMOCLES-MIB is a private MIB (enterprise OID 21796) for a remote environmental/facility monitoring unit, reporting binary inputs, controllable outputs, and analog sensor readings. Its input table records state, name, alarm setup/state, and a transition counter per binary input, an output table records state, name, and type per controllable output, and a sensor table records state, name, a display string, scaled and raw values, an identifier, and a unit label per analog sensor. As a hardware-status MIB it lets a facilities team monitor a mix of digital alarm inputs (door, water, smoke) and analog readings (temperature, humidity) from one unit, and remotely actuate outputs. It is deployed on this vendor's remote environmental/facility monitoring unit. Engineers can download the DAMOCLES-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in DAMOCLES-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

Monitoring Examples

A facilities team monitors sensValue alongside inpAlarmState to catch an environmental fault — combining a raw temperature reading with a discrete door-open alarm — from a single remote monitoring unit.

How to Use in IPNetwork Monitor

Example using tsAlarmsPresent OID:

Select a Remote environmental/facility monitoring unit 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 tsAlarmsPresent into the Find box to locate it in the OID tree, then select it and click OK. The present number of active alarm conditions. 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 Gauge32-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.

tsAlarmTable	1.3.6.1.4.1.21796.3.4.50.2		not-accessible	A list of alarm table entries. The table contains zero, one, or many rows at any moment, depending upon the number of alarm conditions in effect. The table is initially empty at agent startup. The agent creates a row in the table each time a condition is detected and deletes that row when that condition no longer pertains. The agent creates the first row with tsAlarmId equal to 1, and increments the value of tsAlarmId each time a new row is created, wrapping to the first free value greater than or equal to 1 when the maximum value of tsAlarmId would otherwise be exceeded. Consequently, after multiple operations, the table may become sparse, e.g., containing entries for rows 95, 100, 101, and 203 and the entries should not be assumed to be in chronological order because tsAlarmId might have wrapped. The number of rows in the table at any given time is reflected by the value of tsAlarmsPresent.
