It provides fast and easy active end-to-end functional testing\nof all the components in Data Center and Cloud infrastructures.\nArachne is able to detect intra-DC, inter-DC, DC-to-Cloud, and\nDC-to-External-Services issues by generating minimal traffic:\n\n- Reachability\n- Round-trip and 1-way latency\n- Silent packet drops and black holes\n- Jitter (average of the deviation from the network mean latency)\n- PMTU or Firewall issues too related possibly to network config changes\n(accidental or not)\n- Whether network-level SLAs are met\n\n## Usage\n\nThere are two ways to use the Arachne package.\n\n### As a standalone program\nRun Arachne as a standalone program (it's Debian packaged already too).\n\n### As a library in your own program\nImport this package and call Arachne from your program/service with\n```go\n    arachne.Run(config, arachne.ReceiverOnlyMode(false))\n```\nwhere the option provided above is among the few optional ones.\n\n\nBelow is the list of all the CLI options available, when Arachne is\nused as a standalone program. The default options should be good\nenough for most users.\n\n```\n$ arachne --help\n\n____________________________________________________________/\\\\\\______________________________________\n ___________________________________________________________\\/\\\\\\______________________________________\n  ___________________________________________________________\\/\\\\\\______________________________________\n   __/\\\\\\\\\\\\\\\\\\_____/\\\\/\\\\\\\\\\\\\\___/\\\\\\\\\\\\\\\\\\________/\\\\\\\\\\\\\\\\_\\/\\\\\\__________/\\\\/\\\\\\\\\\\\_______/\\\\\\\\\\\\\\\\__\n    _\\////////\\\\\\___\\/\\\\\\/////\\\\\\_\\////////\\\\\\_____/\\\\\\//////__\\/\\\\\\\\\\\\\\\\\\\\__\\/\\\\\\////\\\\\\____/\\\\\\/////\\\\\\_\n     ___/\\\\\\\\\\\\\\\\\\\\__\\/\\\\\\___\\///____/\\\\\\\\\\\\\\\\\\\\___/\\\\\\_________\\/\\\\\\/////\\\\\\_\\/\\\\\\__\\//\\\\\\__/\\\\\\\\\\\\\\\\\\\\\\__\n      __/\\\\\\/////\\\\\\__\\/\\\\\\__________/\\\\\\/////\\\\\\__\\//\\\\\\________\\/\\\\\\___\\/\\\\\\_\\/\\\\\\___\\/\\\\\\_\\//\\\\///////___\n       _\\//\\\\\\\\\\\\\\\\/\\\\_\\/\\\\\\_________\\//\\\\\\\\\\\\\\\\/\\\\__\\///\\\\\\\\\\\\\\\\_\\/\\\\\\___\\/\\\\\\_\\/\\\\\\___\\/\\\\\\__\\//\\\\\\\\\\\\\\\\\\\\_\n        __\\////////\\//__\\///___________\\////////\\//_____\\////////__\\///____\\///__\\///____\\///____\\//////////__\n\n\nUsage: arachne [--foreground] [-c=\u003cconfig_file\u003e] [--receiver_only] [--sender_only]\n\nArachne is a packet loss detection system and an underperforming path detection\nsystem for Data Center and Cloud infrastructures.\n\nOptions:\n  -v, --version                                     Show the version and exit\n  --foreground=false                                Force foreground mode\n  -c, --config_file=\"/usr/local/etc/arachne/arachne.yaml\"     Config file path\n  (default: /usr/local/etc/arachne/arachne.yaml)\n  --receiver_only=false                             Force TCP receiver-only mode\n  --sender_only=false                               Force TCP sender-only mode\n```\n\n\n### Note on required privileges to run\n\nArachne is granted access to raw sockets without the need to run with sudo or\nas root user, by being granted `CAP_NET_RAW` capability\n(see: [capabilities][]).\n\n\n### Note on BPF filtering\n\nWhen receiving packets, Arachne attempts to apply a BPF filter to the raw socket\nso that processing of packets occurs on a much smaller set (ones destined\nspecifically for Arachne agent testing). This is currently supported only on\nLinux and thus performance will be worse on BSD-based systems where a larger\nnumber of packets must be inspected.\n\n\u003chr\u003e\n\nReleased under the [MIT License](LICENSE.md).\n\n\n[doc-img]: https://godoc.org/github.com/uber/arachne?status.svg\n[doc]: https://godoc.org/github.com/uber/arachne\n[ci-img]: https://travis-ci.org/uber/arachne.svg?branch=master\n[ci]: https://travis-ci.org/uber/arachne\n[capabilities]: http://linux.die.net/man/7/capabilities\n[gorep-img]: https://goreportcard.com/badge/github.com/uber/arachne\n[gorep]: https://goreportcard.com/report/github.com/uber/arachne\n","funding_links":[],"categories":["Go","networking"],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fuber%2Farachne","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fuber%2Farachne","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fuber%2Farachne/lists"}
