Miscellaneous > Demo Probe

Demo Probe

The Demo probe type is useful for building demo maps. It generates random data for the traffic on all its links, so that there is something to look at. These traffic data are chartable, as well, and can be used for demonstrating strip charts.

The device also toggles between the UP/OK and Down state when manually reprobed. Consequently, it's also easy to show what happens when a device goes down, especially for manual dependencies.

For simple maps, the parameters below can be set to zero. To create complicated, heavily-interconnected demonstration maps, try setting the parameters to 10 and 50, respectively.

Link Count is the number of interfaces to create when first adding the device to the map.

Loop % is the percentage of links that should connect themselves to subnets that are already present on the map.

Miscellaneous > Legacy > Basic OID (v2c)

SNMP - Basic OID (v2c)

This is a legacy probe, provided for compatibility with InterMapper Traditional and older versions of InterMapper (< 4.4). If you are using InterMapper server, please use the Basic OID probe instead and set the probe's SNMP version to SNMP v2 in the Probe Info window.

This probe lets you monitor a single, user-defined MIB variable. It uses SNMPv2c.

Object Name is the name of the value that you want to monitor. This parameter is optional; the "object name" value only customizes the display in the popup window and chart legend.

Object ID is the object identifier (OID) of the value that you want to monitor. If you wish to retrieve the value of a MIB variable that is not in a table, the OID must end with ".0" (e.g. "1.3.6.1.2.1.1.1.0").

Miscellaneous > Legacy > Cisco (v2c)

SNMP - Cisco (v2c)

This is a legacy probe, provided for compatibility with InterMapper Traditional and older versions of InterMapper (< 4.4). If you are using InterMapper server, please use the Cisco - Process and Memory Pool probe instead and set the probe's SNMP version to SNMP v2 in the Probe Info window.

This probe monitors the CPU and Memory utilization of a Cisco router using SNMPv2c.

CPU Busy - Alarm is the ALARM threshold for CPU utilization. If the average percentage of CPU usage over a 1 minute interval exceeds this threshold, the device will enter the Alarm state.

CPU Busy - Warning is the WARNING threshold for CPU utilization. If the average percentage CPU usage over a 1 minute interval exceeds this threshold, the device will enter the Warning state.

Low Memory - Alarm is the ALARM threshold for the amount of free memory remaining (in bytes). If the free memory drops below this threshold, the device will enter the Alarm state.

Low Memory - Warning is the WARNING threshold for the amount of free memory remaining (in bytes). If the free memory drops below this threshold, the device will enter the Warning state.

Miscellaneous > Legacy > SNMP v2c

SNMP v2c

This is a legacy probe, provided for compatibility with InterMapper Traditional and older versions of InterMapper (< 4.4). If you are using InterMapper server, please use the SNMP MIB-II probe instead and set the probe's SNMP version to SNMP v2 in the Probe Info window.

The SNMP v2c probe retrieves MIB-II information from the device. This includes sysLocation, sysContact, and sysUptime from the system group, and traffic (bytes/second, packets/second, errors/minute) for each of the interfaces.

It also uses the 64-bit counters for interface traffic stats to provide accurate information (without rollover) on very high speed links.

Miscellaneous > Nagios > Nagios Plugin

Nagios Plugin

This probe lets you specify a Nagios plugin. InterMapper invokes the plugin and uses the exit value to set the condition of the device. It uses the performance data returned by the plugin to create a nice display of chartable data. The Plugin parameter below should be the same command line (including arguments) you would use to test the plugin manually. You may enter \${ADDRESS} and it will be replaced with the device's IP address, and \${PORT} will be replaced by the port specified for the probe.

This probe expects the plugin to be in the Tools sub-directory of the InterMapper Settings directory.

Miscellaneous > Non Polling

Non-Polling

The Non-polling probe does not cause any action to occur. This probe is often used as a placeholder for a device, because this probe does not count against the number of devices being monitored.

Miscellaneous > Prototype SNMP Probe

Prototype SNMP Probe

This probe demonstrates an InterMapper Custom SNMP probe, and many of the features that are described in the Custom Probes section of the Developer Guide. If you have questions about this probe, please contact us.

This probe probably isn't really useful for production work. However, it provides an example of various techniques available in custom SNMP probes.

It shows how to retrieve SNMP values from a device by specifying their OIDs and how to display those values in the device's Status Window.

The probe also has thresholds for setting the device into alarm or warning.

In this example, the device has will go into alarm or warning if it has been rebooted recently (controlled by the RebootAlarm and RebootWarn parameters - two and three minutes, by default) or if there aren't as many interfaces as expected in the ifTable (controlled by the ExpectedInterfaces parameter.)

The parameters are:

RebootAlarm Put the device into alarm if the sysUptime is less than this many minutes.

RebootWarn Put the device into warning if the sysUptime is less than this many minutes.

ExpectedInterfaces Put the device into warning if the the ifNumber is greater or equal to this value.

In addition, this probe shows:

Miscellaneous > TCP Check

SNMP - TCP Check

This probe generates an alarm if the count of TCP connections is greater than the "Allowed TCP Connections" parameter. This probe can be used to detect people telnetting into a box that shouldn't have connections (perhaps, a router that might be attacked from outside your network).

This SNMP probe retrieves the device's 'tcpCurrEstab' MIB variable and compares its value to the maximum number of TCP connections allowed. If the number of established TCP connections exceeds the limit, this probe will put the device into "Alarm" status.

Allowed TCP Connections is the threshold for the number of TCP connections allowed. If the number of connections exceeds this value, the device will alarm.
