Alerts & Reports

Alerts & Reports generate email notifications based on QoS parameters or SIP error conditions. It includes daily reports, ad hoc reports, and stores all generated items in history.

Emails use PHP's "mail" function, relying on the server's MTA (e.g., Exim, Postfix, Sendmail). Configure MTA per your Linux distribution documentation.

Process alerts via a PHP script in crontab:

For CentOS & Debian: 

echo "* * * * * root php /var/www/html/php/run.php cron" >> /etc/crontab

(Adjust path to run.php based on VoIPmonitor GUI installation.)

Reload crontab: killall -HUP cron (or crond).

Configure Alerts

Email alerts trigger on SIP protocol or RTP QoS metrics. Types: RTP alerts and SIP signaling.

Common filters: Call duration, IP addresses, numbers, and email recipients.

  • RTP Alerts: Trigger on MOS, packet loss, jitter, delay, one-way calls (answered but one RTP stream missing), or missing RTP (answered but both streams missing). Alert if thresholds exceeded and incidents > set value or CDR percent > threshold.

  • SIP Response Alerts: Trigger on SIP response codes. Empty response: All call attempts per filters. Response 0: Unreplied INVITEs.

  • Filters:
 - IP/Number Group: Apply to defined groups (from Groups menu).
 - IP Addresses/Numbers: Individual IPs, numbers, or ranges (delimited by Enter).
 - Email Group: Send to group-defined emails.
 - Emails: Individual emails (delimited by Enter).

Sent Alerts

Sent alerts are saved in history, matching email content.

Parameters table shows QoS metrics with bad values highlighted.

CDR records table lists cases, with alert flags: (M)OS, (J)itter, (P)acket loss, (D)elay.
