[edit] Description

Alerts functionality is dedicated to taking actions about your system issues which may cause a problem. You may block User, disable Provider, change LCR for User or simply send a notification to specified Group of Contacts.

You are able to follow these parameters:

  • ASR – Answer-Seizure Ratio (percent)
  • ACD – Average Call Duration (in seconds)
  • PDD – Average Post Dial Delay. The time between punching in the last digit of a telephone number and receiving a ring or busy signal (in seconds)
  • TTC (Time to Connect)(DURATION-BILLSEC) – Average time between receiving a ring signal and answer to the call (in seconds)
  • BILLSEC – Sum of calls bilsec (in seconds)
  • TOTAL CALLS – Sum of all calls.
  • ANSWERED CALLS – Sum of answered calls.
  • NOT ANSWERED CALLS – Sum of not answered calls (FAILED, BUSY, NO ANSWER).
  • SIMULTANEOUS CALLS – Number of simultaneous calls (only applies to users and providers).
  • PRICE SUM – Sum of calls price (only applies to users and providers).
  • HGC (absolute) – Sum of calls, which ended with a specific Hangupcause code. The HGC has to be set in the HGC field (it appears once Parameter: HGC is chosen).
  • HGC (percent) – Percent of calls, which ended with a specific Hangupcause code. The HGC has to be set in the HGC field (it appears once Parameter: HGC is chosen).
  • REGISTRATION - Device registration status (either registered or not).

And it is possible to make actions for these types of MOR Objects or send notification about it:

  • Users
    • All
    • Postpaid
    • Prepaid
    • One User
  • Providers
  • Devices
  • Destinations
    • One Destination by prefix.
    • Few Destinations by prefix and % sign. Eg. 93%, 3706% and so on.
  • Destinations Groups
  • System
    • Any call made will be assigned to System object (even unauthenticated calls). Useful for general System monitoring.



[edit] Usage

Go to ADDONS –> Monitorings –> Alerts

File:alerts_path.png

Here you can see list of all created Alerts and their main information like is Alert active? When it was Raised/Cleared last time? What value was at Alert/Clear...

NOTE: Object Type, Object Name, Parameter, Alert Type cannot be changed once Alert is created.

  • Ignore if Calls <= – indicate calls sum when system should ignore Alert if calls sum is less than written (if 0, Alert will not be ignored).
  • Ignore if Calls >= – indicate calls sum when system should ignore Alert if calls sum is more than written (if 0, Alert will not be ignored).
  • Group to Notify – select Group of Contacts who should be informed about Alert/clear.

Period

You can select different time periods for each alert. This period defines time period which activity have to be checked.

Note: period has no effect when parameter SIMULTANEOUS CALLS is chosen.

Comment – additional notes.

[edit] Alert vs Clear

Example with CPU Load just to demonstrate what is Alert and what is Clear and proper usage of them.

[edit] Examples

[edit] Send notification and change LCR on Alert

Parameter: TOTAL CALLS
Object Type: User
Object Name: Prepaid
Alert if >=: 300
Clear if <=: 200
LCR on alert: secondary LCR
LCR on clear: Restore Original
Group to Notify: support group
Notify on Alert via Email: checked
Period: 1h

This Alert monitors all Calls done by Prepaid Users. If a Prepaid User makes more than 300 Calls during one hour period, his LCR will be changed to secondary LCR and Email notification will be sent to every contact on support group.
If User's Call count drops below 200 calls during one hour period, his LCR will be restored to original LCR

[edit] Block user when simultaneous calls are detected

Parameter: SIMULTANEOUS CALLS
Object Type: User
Object Name: All
Alert if >=: 2
Group to Notify: administration
Notify on Alert via Email: checked
Disable Object: checked
Disable Clear: checked

This Alert monitors simultaneous calls done by all Users. If a User makes more than (or equal to) 2 simultaneous Calls to the same destination, his account will be suspended and Email notification will be sent to every contact on administration group.
This alert will no be cleared automatically and user will stay suspended even if no more simultaneous calls are present.

[edit] Block user if it spends more than 50EUR in 24h

Parameter: PRICE SUM
Object Type: User
Object Name: All
Alerf if >= 50
Group to Notify: administration
Notify on Alert via Email: checked
Disable Object: checked
Disable Clear: checked
Check last: 24 h


[edit] Alerts triggered by other Alerts

Administrators are able to create alerts that depend on other alerts. What that means is, that you are able to create an alert that is triggered by a set or a subset of other alerts.

Example:

  • Alert 1 is triggered when a specific user's ACD drops below ten seconds.
  • Alert 2 is triggered when a the same user's Device's ASR drops below 50%.
  • Alert 3 is triggered when both Alert 1 and Alert 2 is triggered, so that the technicians are notified.

In order to set up such a chain of events, you should first create Alert 1 and Alert 2.

Then, you should set up Alert 3.

File:Alert_group_parameter.png‎

  • Configure your alert as usual, but instead of a specific parameter choose GROUP.
  • Then, add the alert dependencies using the shown interface.



File:Alert_group_alert.png‎

  • Set a number of alerts, that, when reached will trigger the alert.



File:Alert_group_clear.png‎

  • Finally set up a number of alerts that will clear your alert.

These alerts can also be nested, without worrying about circular-dependencies, MOR simply will not let you make them.
