Examples of representing a project or community include using an official project e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. Representation of a project may be further defined and clarified by project maintainers. 34 | 35 | ## Enforcement 36 | 37 | Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project team at devops@hipages.com.au. The project team will review and investigate all complaints, and will respond in a way that it deems appropriate to the circumstances. The project team is obligated to maintain confidentiality with regard to the reporter of an incident. Further details of specific enforcement policies may be posted separately. 38 | 39 | Project maintainers who do not follow or enforce the Code of Conduct in good faith may face temporary or permanent repercussions as determined by other members of the project's leadership. 40 | 41 | ## Attribution 42 | 43 | This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4, available at [http://contributor-covenant.org/version/1/4][version] 44 | 45 | [homepage]: http://contributor-covenant.org 46 | [version]: http://contributor-covenant.org/version/1/4/ 47 | -------------------------------------------------------------------------------- /Dockerfile: -------------------------------------------------------------------------------- 1 | FROM alpine:3.21.2 2 | 3 | ARG BUILD_DATE 4 | ARG VCS_REF 5 | ARG VERSION 6 | 7 | COPY php-fpm_exporter / 8 | 9 | EXPOSE 9253 10 | ENTRYPOINT [ "/php-fpm_exporter", "server" ] 11 | 12 | LABEL org.label-schema.build-date=$BUILD_DATE \ 13 | org.label-schema.name="php-fpm_exporter" \ 14 | org.label-schema.description="A prometheus exporter for PHP-FPM." \ 15 | org.label-schema.url="https://hipages.com.au/" \ 16 | org.label-schema.vcs-ref=$VCS_REF \ 17 | org.label-schema.vcs-url="https://github.com/hipages/php-fpm_exporter" \ 18 | org.label-schema.vendor="hipages" \ 19 | org.label-schema.version=$VERSION \ 20 | org.label-schema.schema-version="1.0" \ 21 | org.label-schema.docker.cmd="docker run -it --rm -e PHP_FPM_SCRAPE_URI=\"tcp://127.0.0.1:9000/status\" hipages/php-fpm_exporter" 22 | -------------------------------------------------------------------------------- /LICENSE: -------------------------------------------------------------------------------- 1 | Apache License 2 | Version 2.0, January 2004 3 | http://www.apache.org/licenses/ 4 | 5 | TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION 6 | 7 | 1.

Valid levels: [debug, info, warn, error, fatal] (default "error") | `PHP_FPM_LOG_LEVEL` | info | 67 | 68 | ### Why `--phpfpm.fix-process-count`? 69 | 70 | `php-fpm_exporter` implements an option to "fix" the reported metrics based on the provided processes list by PHP-FPM. 71 | 72 | We have seen PHP-FPM provide metrics (e.g. active processes) which don't match reality. 73 | Specially `active processes` being larger than `max_children` and the actual number of running processes on the host. 74 | Looking briefly at the source code of PHP-FPM it appears a scoreboard is being kept and the values are increased/decreased once an action is executed. 75 | The metric `active processes` is also an accumulation of multiple states (e.g. Reading headers, Getting request information, Running). 76 | Which shouldn't matter and `active processes` should still be equal or lower to `max_children`. 77 | 78 | `--phpfpm.fix-process-count` will emulate PHP-FPMs implementation including the accumulation of multiple states. 79 | 80 | If you like to have a more granular reporting please use `phpfpm_process_state`. 81 | 82 | * https://bugs.php.net/bug.php?id=76003 83 | * https://stackoverflow.com/questions/48961556/can-active-processes-be-larger-than-max-children-for-php-fpm 84 | 85 | ### CLI Examples 86 | 87 | * Retrieve information from PHP-FPM running on `127.0.0.1:9000` with status endpoint being `/status` 88 | ``` 89 | php-fpm_exporter get 90 | ``` 91 | 92 | * Retrieve information from PHP-FPM running on `127.0.0.1:9000` and `127.0.0.1:9001` 93 | ``` 94 | php-fpm_exporter get --phpfpm.scrape-uri tcp://127.0.0.1:9000/status,tcp://127.0.0.1:9001/status 95 | ``` 96 | 97 | * Run as server with 2 pools: 98 | ``` 99 | php-fpm_exporter server --phpfpm.scrape-uri tcp://127.0.0.1:9000/status,tcp://127.0.0.1:9001/status 100 | ``` 101 | 102 | * Run as server and enable process count fix via environment variable: 103 | ``` 104 | PHP_FPM_FIX_PROCESS_COUNT=1 go run main.go server --web.listen-address ":12345" --log.level=debug 105 | ``` 106 | 107 | ### Docker Examples 108 | 109 | * Run docker manually 110 | ``` 111 | docker pull hipages/php-fpm_exporter 112 | docker run -it --rm -e PHP_FPM_SCRAPE_URI="tcp://127.0.0.1:9000/status,tcp://127.0.0.1:9001/status" hipages/php-fpm_exporter 113 | ``` 114 | 115 | * Run the docker-compose example 116 | ``` 117 | git clone git@github.com:hipages/php-fpm_exporter.git 118 | cd php-fpm_exporter/test 119 | docker-compose -p php-fpm_exporter up 120 | ``` 121 | You can now access the following links: 122 | 123 | * Prometheus: http://127.0.0.1:9090/ 124 | * php-fpm_exporter metrics: http://127.0.0.1:9253/metrics 125 | 126 | [![asciicast](https://asciinema.org/a/1msR8nqAsFdHzROosUb7PiHvf.png)](https://asciinema.org/a/1msR8nqAsFdHzROosUb7PiHvf) 127 | 128 | ### Kubernetes Example 129 | 130 | TBD 131 | 132 | ##
