Monitoring uptime

Posted On: September 10, 2005 - 16:25 by Admin

Error control (EC) is a very powerful feature that helps you quickly locate a problem, prevents superfluous Alerting and incorrect interpretation of a problem. EC tries to find the root-cause of a device that doesn’t respond to status requests anymore.

To be more precise, the above means that if a "No response" event occurs for a device, EC tries to find out whether the event is caused by a definite failure of the device itself OR by another device experiencing problems in the chain of devices (network paths) between the station running Monitor one (the "ThisStation" object on the map) and the device!

EC uses the information provided by the network map (connections and device types) to find out which device causes a "No response" event. It is therefore extremely important to set up your network maps as accurately/factually as possible. If a device "A" is physically connected to device "B", draw a link between them on your network map accordingly!

Without Error control

By a failure of Router2, seven devices get the Down status. If alerting by email is enabled, the network manager receives 7 email alerts (worst case) from which 6 are superfluous!

Without Error control

Error control enabled

Only Router2 and PC5 get the "No response" status. All other devices get the "Unknown" status (blue tick). The network manager only receives 2 alert emails.

With Error control

PC5 gets the Down status because it is not connected to the switch. Monitor one gets no response from PC5 but is unable to determine the root cause of the down event because of the lack of map information (unknown network path) and acts accordingly.

Enabling Error control

Enabling Error control is simple; just add the "ThisStation" object (predefined) to the network map and add a link between the "ThisStation" object and the switch or hub to which it is actually connected. The "ThisStation" object is a special purpose object representing the physical workstation (or server) that runs the Monitor one software and is the key object for the "Error control" feature.

News

InfoFineConnection is pleased to announce the availability of the new stable Monitor one version FP1.106.391 (February 2008).
ChartsFor superior trending and long-term analysis, Monitor one can act as a "front end" for RRD. RRD is a system to store and display time-series data. The RRD can also perfectly be used for exporting logged trending data to text files for use in spreadsheets or databases. More...

PDAMonitor one provides an interface to messaging gateway systems, making it easy to send alert messages to pagers, mobile phones, PIMs and wireless devices.
MonitorThe Monitor one "Desktop" option allows you to save Monitor one desktop configurations to the database for quick access later.
CertificateThe new version also comes with a new licensing policy. The required license type is now only determined by the number of device objects on the network map from which you want to monitor uptime. The number of concurrently running Shooters (SNMP monitors) is now "unlimited" in all versions (was dependent of the license type!)
Font_and_ColorThe new version allows you to define the font name, size and color for object labels on the network map.
