{| class="wikitable"
|-
! Value !! When to Use
|-
| '''1''' (default) || Sequential processing
|-
| '''2-4''' || Reports delayed, database has capacity
|-
| '''4-8''' || Heavy report load, standard database
|-
| '''8-16''' || Dedicated database server
|}


Chart creation dialog allows custom charts with filters on numbers, IP, RTP stats.
{{Note|1=<code>cron/reports</code> controls report/alert generation. <code>parallel tasks</code> controls audio merging (unrelated).}}


[[File:report-chartedit.png]]
== CSV Export via Crontab ==


Preview results or send test emails via buttons.
# Set '''Folder for export CSV''' in '''GUI > Settings > System Configuration > Advanced'''
# Create task in '''GUI > Settings > Crontab Scheduler'''
# Ensure web server user has write access to export folder


[[File:report-chartbuttons.png]]
For custom formats, use [[WEB_API|Web API]] instead.


[[File:report-preview.png]]
== Troubleshooting ==


=== Report Generator ===
=== Reports Timeout for Large Date Ranges ===


Creates reports from historical data by criteria.
'''Symptom:''' Reports take 30+ seconds then timeout, especially with IP group filters.


* "Only CDR with RTP" checkbox: Reports connected calls only (ASR always 100%) or all CDRs.
'''Solution:''' Disable the '''"include proxy"''' checkbox next to caller/called IP group field in report configuration. This option causes expensive database joins.


[[File:report-generatorform.png]]
=== Timezone Mismatch ===


Results table appears below form after selecting date, IP ranges, QoS parameters.
'''Symptom:''' Scheduled reports run at wrong time or don't trigger.


[[File:reports-results.png]]
'''Solution:'''
<syntaxhighlight lang="bash">
# Check OS timezone
timedatectl


=== Call Summary ===
# Align with GUI (Settings > System Configuration > National > Timezone)
timedatectl set-timezone Europe/Prague
</syntaxhighlight>


Overview grouped by source/destination IPs, focusing on signaling metrics: ASR, ACD, total duration, call count. Toolbar filters by date range, source/destination numbers.
=== Blank Reports During Daylight Savings Time ===


[[File:reports-callsummary.png]]
'''Symptom:''' Reports empty when using named timezones (e.g., <code>America/Los_Angeles</code>) during DST transitions.


==== Description of the columns in the export ====
'''Workaround:''' Change GUI timezone to fixed UTC offset (e.g., <code>GMT-8</code> instead of <code>America/Los_Angeles</code>).

Reports

VoIPmonitor provides multiple report types for analyzing call data, quality metrics, and generating scheduled summaries.

Report Type Purpose Output
Daily Email Reports Scheduled summaries (RTP, CPS, charts, CDR summary) Email
Report Generator Ad-hoc historical analysis GUI, CSV
Call Summary Aggregated by IP (ASR, ACD, duration) GUI, CSV
QoS Report RTP quality metrics (MOS, jitter, loss) GUI
CDR Simplified Quick CDR view with filters GUI

Prerequisites

Reports require a working cron job for scheduled delivery. See Alerts - Email Configuration for cron setup and MTA requirements.

ℹ️ Note: For scheduled reports, ensure cleandatabase in /etc/voipmonitor.conf exceeds your longest report period (e.g., >30 days for monthly reports). See Data_Cleaning.

Daily Email Reports

Navigate to GUI > Reports > Configure Daily Reports to create scheduled reports.

RTP Daily Report

Summarizes RTP metrics: MOS, packet loss, jitter, delay (PDV), duration, one-way, and missing RTP.

CPS Daily Report

Reports maximum and average Calls Per Second (CPS) over the selected period.

Daily Charts Report

Generates visual charts of call metrics filtered by criteria (SIP trunks, numbers, IP).

Time Range Settings:

Period Configuration
Daily "last day 1"
Weekly "this week from Monday" + enable "previous interval"
Monthly "previous month"

Creating Chart Templates:

  1. Navigate to GUI > Reports > Configure Daily Reports > Charts
  2. Click chart creation button
  3. Configure filters (CDR criteria, IP addresses, numbers)
  4. Select metrics (MOS, packet loss, jitter, concurrent calls)
  5. Save as chart template
  6. Attach template to scheduled report

💡 Tip: Schedule resource-intensive reports (30-day charts) during off-peak hours to reduce database load.

CDR Summary Report

Daily summary grouped by various criteria with optional billing costs.

Summary Types:

Type Description
source IP / destination IP Group by IP address
source number / destination number Group by telephone number
Called/Caller number group Group by predefined Telephone Number Groups

Configuration:

  1. Select CDR summary as report type
  2. Choose Summary type from dropdown
  3. Filter by SIP response in Common tab (e.g., %OK%, 404%)
  4. Enable Price columns for billing costs (requires Billing Configuration)

ℹ️ Note: For multiple SIP response codes, create separate reports for each code pattern. A single report cannot aggregate multiple response types.

NPA-NXX Prefix Reporting:

  1. Create telephone number groups in GUI > Groups > Tel. numbers for each prefix
  2. Include country code variants (e.g., both 1202333 and 202333)
  3. Use Called number group summary type
  4. Select groups in filter field

Report Generator

GUI > Reports > Report Generator - Creates ad-hoc reports from historical data.

  • "Only CDR with RTP" checkbox: Reports only connected calls (ASR always 100%)
  • Filter by date range, IP, numbers, QoS parameters
  • Export results to CSV

⚠️ Warning: Limitation: Cannot combine "group by customer" AND "destination country" filters in one report. Create separate reports for each customer with both filters applied.

Call Summary

GUI > Reports > Call Summary - Overview grouped by source/destination IP.

Key Metrics: ASR, ACD, NER, total duration, call count.

Export Column Reference

Basic Metrics:

Column Description
sipip Source IP address
cnt_all / cnt_connected Total / connected CDR count
duration_all Sum of connected seconds
asr_all / acd_all / ner_all Answer Seizure Ratio / Avg Call Duration / Network Effectiveness Ratio
mos_all MOS average (min of caller/called)
pdd_all Post Dial Delay (ms)
jitter_all / delay_all Average jitter / median PDV
packets_lost_all Lost packets count

RTCP Columns: rtcp_maxfr, rtcp_avgfr, rtcp_maxjitter, rtcp_avgjitter, rtcp_maxrtd, rtcp_avgrtd

MOS XR Columns: mos_xr_avg_all, mos_xr_min_all, mos_xr_avg_caller_all, mos_xr_avg_called_all

Silence/Clipping Columns (requires silence detection): mos_silence_avg_all, silence_all, silence_end_all, clipping_all

QoS Report

GUI > Reports > QoS - Similar to Call Summary but emphasizes RTP metrics.

Multi-hop Troubleshooting:

  1. Set time range for issue period
  2. Use "per caller IP" or "per called IP" filter
  3. Compare MOS scores across IPs to identify degraded segment
  4. Combine with dashboard MOS panels for visual timeline

Regulatory Reporting

Metric Column Description
Answer Seizure Ratio asr_all % of calls connecting successfully
Post Dial Delay pdd_all Call setup time (ms)
Mean Opinion Score mos_all Voice quality (1-5)

ℹ️ Note: Dropped Call Ratio (DCR) is NOT available. Submit a feature request with your specific formula if needed.

Parallel Processing Configuration

The cron/reports setting controls parallel report generation.

Location: GUI > Settings > System Configuration > Advanced

Value When to Use
1 (default) Sequential processing
2-4 Reports delayed, database has capacity
4-8 Heavy report load, standard database
8-16 Dedicated database server

ℹ️ Note: cron/reports controls report/alert generation. parallel tasks controls audio merging (unrelated).

CSV Export via Crontab

  1. Set Folder for export CSV in GUI > Settings > System Configuration > Advanced
  2. Create task in GUI > Settings > Crontab Scheduler
  3. Ensure web server user has write access to export folder

For custom formats, use Web API instead.

Troubleshooting

Reports Timeout for Large Date Ranges

Symptom: Reports take 30+ seconds then timeout, especially with IP group filters.

Solution: Disable the "include proxy" checkbox next to caller/called IP group field in report configuration. This option causes expensive database joins.

Timezone Mismatch

Symptom: Scheduled reports run at wrong time or don't trigger.

Solution: 

# Check OS timezone
timedatectl

# Align with GUI (Settings > System Configuration > National > Timezone)
timedatectl set-timezone Europe/Prague

Blank Reports During Daylight Savings Time

Symptom: Reports empty when using named timezones (e.g., America/Los_Angeles) during DST transitions.

Workaround: Change GUI timezone to fixed UTC offset (e.g., GMT-8 instead of America/Los_Angeles).

Monthly Reports Fail in Distributed Setups

Symptom: Monthly reports don't generate in multi-sensor environments.

Solution: Configure partition operations to prevent database lock conflicts:

On sniffer sensors: 

# /etc/voipmonitor.conf
disable_partition_operations = yes

On main server: 

# /etc/voipmonitor.conf
disable_partition_operations = no
partition_operations_enable_fromto = 4-5

⚠️ Warning: Avoid scheduling reports during partition maintenance window (default 01:00-01:10 AM). Schedule 15-30 minutes before or after.

Missing daily_reports_sended Table

Symptom: Cannot enable/create daily reports in GUI.

Solution: 

CREATE TABLE `daily_reports_sended` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `daily_reports_id` int(11) NOT NULL,
  `day` date NOT NULL,
  `subject` text DEFAULT NULL,
  `content` mediumtext DEFAULT NULL,
  `send_time` datetime DEFAULT NULL,
  `send_email` text DEFAULT NULL,
  PRIMARY KEY (`id`),
  KEY `fk__daily_reports_sended__daily_reports` (`daily_reports_id`),
  CONSTRAINT `fk__daily_reports_sended__daily_reports`
    FOREIGN KEY (`daily_reports_id`) REFERENCES `daily_reports` (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

Email Shows "Sent" But Not Delivered

Symptom: GUI shows success but email never arrives.

Solution: Check for missing MTA: 

# Check error log
tail -n 50 /var/log/httpd/error_log | grep sendmail

# Install MTA if missing
apt-get install postfix  # Debian/Ubuntu
yum install postfix      # RHEL/CentOS
