    • Catch-UP
    • VOD

Script-Probe – is a system component intended for importing data from outside facilities or systems.

Data input is provided using user-generated scripts. The service uses pre-installed evaluators for interacting with scripts, and Script-Probe uses IP-address and information input protocol. The system gathers various metrics and translates them into the aggregation module for further analysis.

This system component helps control status changes of infrastructure objects and systems. That is, the MultiProbe system makes it possible, beside controlling signals, to monitor the hardware and the infrastructure in general.

All types of facilities with open interaction protocols are supported:

  • Switches

Product Features:

Virtual correlation services

The system allows for operating with upper-level monitoring objects which are represented as virtual providers of “services” that can be assessed in terms of their status by configuring the interrelation of monitoring objects, those that have their status constantly monitored.

«Virtual Service» - is an entity the status of which is defined by the function of such monitoring objects that make up this entity.

  • Service status control
  • Channel visualization
  • Customizable correlation of object statuses

User working spaces

A special feature that characterizes MultiProbe system is its focus on the rank-and-file user. Since the system can be fully configured in accordance with own needs, operating any of the product component is an easy and enjoyable task. User desktops allow the creation of a combined single presentation during the process of controlling any objects. Main page of the system is made up of desktops which a user must create and configure for himself. The desktop itself is presented as a space with widgets located in a pattern which is comfortable for the user.

  • Object status panels
  • Value indicators
  • Diagrams of mean values
  • Graphic charts
  • Location and time filters
  • Vidgets of preview images
  • Dissemination paths

Batch operations

With available use of batch operations, the system does not present problems for users if a large numbers of objects must be configured. The whole MultiProbe system is set up to operate with lists that contain searching, sorting and filtering tools, as well as possibilities for configuring available templates to highlighted objects.

This solution allows for a drastic reduction of config period and further system reconfiguration. This functionality allows also for a quick further adjustment of the complex when more sites are added due to the increase of the number of analyzer probes.

In the same vein, all users are gathered in groups so that overall access and alert configurations can be implemented, and corresponding role templates are applied to these groups, with different rights for accessing system locations and segments.

Alarm event templates

This system allows for both using default templates of alarm events and creating own templates out of available user triggers.

While a trigger is formed, the system defines logical predicates, which helps configuring several triggers to react to one alarm event, following different metrics of monitored objects.

The system allows the use of the same metric in different templates, with differing priority settings.
