PHP-FPM Metrics

PHP-FPM Metrics via Telegraf to your Logit.io Stack

Configure Telegraf to ship PHP-FPM metrics to your Logit.io stacks via Logstash.

Install Integration

Please click on the Install Integration button to configure your stack for this source.

Install Telegraf

This integration allows you to configure a Telegraf agent to send your metrics, in multiple formats, to Logit.io.

Choose the installation method for your operating system:

When you paste the command below into Powershell it will download the Telegraf zip file. Once that is complete, press Enter again and the zip file will be extracted into C:\Program Files\InfluxData\telegraf\telegraf-1.31.2.

wget https://dl.influxdata.com/telegraf/releases/telegraf-1.31.2_windows_amd64.zip -UseBasicParsing -OutFile telegraf-1.31.2_windows_amd64.zip 
Expand-Archive .\telegraf-1.31.2_windows_amd64.zip -DestinationPath 'C:\Program Files\InfluxData\telegraf'

Configure the Telegraf input plugin

The configuration file below is pre-configured to scrape the system metrics from your hosts, add the following code to the configuration file /etc/telegraf/telegraf.conf from the previous step.

# Read metrics of phpfpm, via HTTP status page or socket
[[inputs.phpfpm]]
  ## An array of addresses to gather stats about. Specify an ip or hostname
  ## with optional port and path
  ##
  ## Plugin can be configured in three modes (either can be used):
  ##   - http: the URL must start with http:// or https://, ie:
  ##       "http://localhost/status"
  ##       "http://192.168.130.1/status?full"
  ##
  ##   - unixsocket: path to fpm socket, ie:
  ##       "/var/run/php5-fpm.sock"
  ##      or using a custom fpm status path:
  ##       "/var/run/php5-fpm.sock:fpm-custom-status-path"
  ##      glob patterns are also supported:
  ##       "/var/run/php*.sock"
  ##
  ##   - fcgi: the URL must start with fcgi:// or cgi://, and port must be present, ie:
  ##       "fcgi://10.0.0.12:9000/status"
  ##       "cgi://10.0.10.12:9001/status"
  ##
  ## Example of multiple gathering from local socket and remote host
  ## urls = ["http://192.168.1.20/status", "/tmp/fpm.sock"]
  urls = ["http://localhost/status"]
 
  ## Duration allowed to complete HTTP requests.
  # timeout = "5s"
 
  ## Optional TLS Config
  # tls_ca = "/etc/telegraf/ca.pem"
  # tls_cert = "/etc/telegraf/cert.pem"
  # tls_key = "/etc/telegraf/key.pem"
  ## Use TLS but skip chain & host verification
  # insecure_skip_verify = false

Configure the output plugin

Once you have generated the configuration file, you need to set up the output plug-in to allow Telegraf to transmit your data to Logit.io in Prometheus format. This can be accomplished by incorporating the following code into your configuration file:

[[outputs.http]]
  url = "https://@metricsUsername:@metricsPassword@@metrics_id-vm.logit.io:@vmAgentPort/api/v1/write"
  data_format = "prometheusremotewrite"
 
  [outputs.http.headers]
    Content-Type = "application/x-protobuf"
    Content-Encoding = "snappy"

Start Telegraf

From the location where Telegraf was installed (C:\Program Files\InfluxData\telegraf\telegraf-1.31.2) run the program providing the chosen configuration file as a parameter:

.\telegraf.exe --config telegraf-demo.conf

Once Telegraf is running you should see output similar to the following, which confirms the inputs, output and basic configuration the application has been started with: Powershell Telegraf information

Telegraf PHP-FPM Overview

For effective monitoring and analysis of PHP-FPM metrics across a distributed environment, it's crucial to deploy a robust and efficient metrics management solution. Telegraf, an open-source server agent designed for collecting and sending telemetry data, is perfectly suited for this role. It's capable of gathering PHP-FPM metrics from a wide array of sources, such as operational PHP-FPM instances, databases, and other relevant applications.

Telegraf features a vast selection of input plugins, enabling users to collect metrics from various sources like CPU usage, memory utilization, network traffic, and more. All of these metrics are critical for understanding PHP-FPM performance. To store and sift through these harvested metrics, organizations can utilize Prometheus, an open-source monitoring and alerting toolkit well-regarded for its flexible querying language and strong data visualization capabilities.

To channel PHP-FPM metrics from Telegraf to Prometheus, organizations must configure Telegraf to output metrics in the Prometheus format, and then set up Prometheus to scrape these metrics from the Telegraf server. This process involves setting up Telegraf to gather PHP-FPM metrics, outputting them in the Prometheus format, configuring Prometheus to retrieve these metrics from the Telegraf server, and then visually interpreting the data using Prometheus's robust querying and graphical visualization tools.

Once the metrics are successfully integrated into Prometheus, further analysis and visualization can be undertaken using Grafana. Grafana, a leading open-source platform recognized for its monitoring and observability capabilities, is fully compatible with Prometheus. It enables users to create dynamic, interactive dashboards for a deeper examination of the metrics data, offering a comprehensive understanding of performance trends and potential issues in the PHP-FPM system.
