10 | In {pve}, you can define external metric servers, which will periodically |
11 | receive various stats about your hosts, virtual guests and storages. | |
d9abb1d6 DC |

13 | Currently supported are: | |
14 | ||
0a3aed9c TL |
15 | * Graphite (see http://graphiteapp.org ) |
16 | * InfluxDB (see https://www.influxdata.com/time-series-platform/influxdb/ ) | |

18 | The external metric server definitions are saved in '/etc/pve/status.cfg', and |
19 | can be edited through the web interface. | |

22 | Graphite server configuration |

08e75d1a | 27 | The default port is set to *2003* and the default graphite path is *proxmox*. |

29 | By default, {pve} sends the data over UDP, so the graphite server has to be |
30 | configured to accept this. Here the maximum transmission unit (MTU) can be | |
31 | configured for environments not using the standard *1500* MTU. | |

33 | You can also configure the plugin to use TCP. In order not to block the |
34 | important `pvestatd` statistic collection daemon, a timeout is required to cope | |
35 | with network problems. | |

43 | {pve} sends the data over UDP, so the influxdb server has to be configured for |
44 | this. The MTU can also be configured here, if necessary. | |

46 | Here is an example configuration for influxdb (on your influxdb server): | |

50 | enabled = true |
51 | bind-address = "0.0.0.0:8089" | |
52 | database = "proxmox" | |
53 | batch-size = 1000 | |
54 | batch-timeout = "1s" | |
0a3aed9c | 55 | ---- |
d9abb1d6 | 56 | |
08e75d1a TL |
57 | With this configuration, your server listens on all IP addresses on port 8089, |
58 | and writes the data in the *proxmox* database |
