Zerto

Plugin: go.d.plugin Module: prometheus

Overview

Monitor Zerto disaster recovery and data protection metrics for efficient backup and recovery management.

Metrics are gathered by periodically sending HTTP requests to Zerto Exporter.

This collector is supported on all platforms.

This collector supports collecting metrics from multiple instances of this integration, including remote instances.

Default Behavior

Auto-Detection

By default, it detects instances running on the local host by trying to connect to known ports that are allocated to exporters. The full list of endpoints is available in the collector's configuration file.

Limits

The default configuration for this integration does not impose any limits on data collection.

Performance Impact

The default configuration for this integration is not expected to impose a significant performance impact on the system.

Metrics

This collector has built-in grouping logic based on the type of metrics.

MetricChartDimension(s)Algorithm
Gaugefor each label setone, the metric nameabsolute
Counterfor each label setone, the metric nameincremental
Summary (quantiles)for each label set (excluding 'quantile')for each quantileabsolute
Summary (sum and count)for each label setthe metric nameincremental
Histogram (buckets)for each label set (excluding 'le')for each bucketincremental
Histogram (sum and count)for each label setthe metric nameincremental

Untyped metrics (have no '# TYPE') processing:

  • As Counter or Gauge depending on pattern match when 'fallback_type' is used.
  • As Counter if it has suffix '_total'.
  • As Summary if it has 'quantile' label.
  • As Histogram if it has 'le' label.

The rest are ignored.

Alerts

There are no alerts configured by default for this integration.

Setup

Prerequisites

Install Exporter

Install Zerto Exporter by following the instructions mentioned in the exporter README.

Configuration

File

The configuration file name for this integration is go.d/prometheus.conf.

You can edit the configuration file using the edit-config script from the Netdata config directory.

cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config go.d/prometheus.conf

Options

The following options can be defined globally: update_every, autodetection_retry.

selector

This option allows you to filter out unwanted time series. Only metrics matching the selector will be collected.

  • Logic: (pattern1 OR pattern2) AND !(pattern3 or pattern4)
  • Pattern syntax: selector.
  • Option syntax:
selector:
allow:
- pattern1
- pattern2
deny:
- pattern3
- pattern4
fallback_type

This option allows you to process Untyped metrics as Counter or Gauge instead of ignoring them.

fallback_type:
counter:
- metric_name_pattern1
- metric_name_pattern2
gauge:
- metric_name_pattern3
- metric_name_pattern4

Examples

Basic

Note: Change the port of the monitored application on which it provides metrics.

A basic example configuration.

jobs:
- name: local
url: http://127.0.0.1:9090/metrics

HTTP authentication

Note: Change the port of the monitored application on which it provides metrics.

Basic HTTP authentication.

Config
jobs:
- name: local
url: http://127.0.0.1:9090/metrics
username: username
password: password

HTTPS with self-signed certificate

Note: Change the port of the monitored application on which it provides metrics.

Do not validate server certificate chain and hostname.

Config
jobs:
- name: local
url: https://127.0.0.1:9090/metrics
tls_skip_verify: yes

Multi-instance

Note: When you define multiple jobs, their names must be unique. Note: Change the port of the monitored application on which it provides metrics.

Collecting metrics from local and remote instances.

Config
jobs:
- name: local
url: http://127.0.0.1:9090/metrics

- name: remote
url: http://192.0.2.1:9090/metrics

Troubleshooting

Debug Mode

To troubleshoot issues with the prometheus collector, run the go.d.plugin with the debug option enabled. The output should give you clues as to why the collector isn't working.

  • Navigate to the plugins.d directory, usually at /usr/libexec/netdata/plugins.d/. If that's not the case on your system, open netdata.conf and look for the plugins setting under [directories].

    cd /usr/libexec/netdata/plugins.d/
  • Switch to the netdata user.

    sudo -u netdata -s
  • Run the go.d.plugin to debug the collector:

    ./go.d.plugin -d -m prometheus
