# netdata configuration for aggregating data from remote hosts # # API keys authorize a pair of sending-receiving netdata servers. # Once their communication is authorized, they can exchange metrics for any # number of hosts. # # You can generate API keys, with the linux command: uuidgen # # ----------------------------------------------------------------------------- # 1. ON SLAVE NETDATA - THE ONE THAT WILL BE SENDING METRICS [stream] # Enable this on slaves, to have them send metrics. enabled = no # The destination to send metrics to. # A space separated list of: # [PROTOCOL:]HOST[%INTERFACE][:PORT] # The first available will get the metrics. # PROTOCOL = tcp or udp (only tcp is supported by masters) # HOST = an IPv4, IPv6 IP, or a hostname. # IPv6 IPs should be given with brackets [ip:address] # INTERFACE = the network interface to use # PORT = the port number or service name (/etc/services) # This communication is not HTTP (cannot be proxied by web proxies). destination = # The API_KEY to use (as the sender) api key = # The timeout to connect and send metrics timeout seconds = 60 # If the destination line above does specify a port, use this default port = 19999 # The buffer to use for sending metrics. # 1MB by default is good for 2-3 seconds of data, so increase this # if you expect latencies. buffer size bytes = 1048576 # If the connection fails, or it disconnects, # retry after that many seconds. reconnect delay seconds = 5 # Attempt to sync the clock the of the master with the clock of the # slave for that many iterations, when starting. initial clock resync iterations = 60 # ----------------------------------------------------------------------------- # 2. ON MASTER NETDATA - THE ONE THAT WILL BE RECEIVING METRICS # # You can have one API key per slave, or the same API key for all slaves. # # All options below are used in this order: # # a) MACHINE_GUID (settings for each machine) # b) API_KEY (settings for the API key) # c) this netdata defaults (as in netdata.conf) # # You can combine the above (the more specific setting will be used). # API key authentication # If the key is not listed here, it will not be able to connect. [API_KEY] # Default settings for the API key # You can disable the API key, by setting this to: no # The default (for unknown API keys) is also: no enabled = no # The default history in entries, for all hosts using this API key. # You can also set it per host below. # If you don't set it here, the history size of the central netdata # will be used default history = 3600 # The default memory mode to be used for all hosts using this API key. # You can also set it per host below. # If you don't set it here, the memory mode of netdata.conf will be used. # Valid modes: # save save on exit, load on start # map like swap (continuously syncing to disks) # ram keep it in RAM, don't touch the disk # none no database (passing through this netdata) default memory mode = ram # Shall we enable health monitoring for the hosts using this API key? # 3 values: # yes enable alarms # no do not enable alarms # auto enable alarms, only when the sending netdata is connected # You can also set it per host, below. # The default is the same as to netdata.conf health enabled by default = auto # postpone alarms for a short period after the sender is connected default postpone alarms on connect seconds = 60 # need to route metrics differently? set these. # the defaults are the ones at the [stream] section #default proxy enabled = yes | no #default proxy destination = IP:PORT IP:PORT ... #default proxy api key = API_KEY # ----------------------------------------------------------------------------- # 3. ON MASTER NETDATA - THE ONE THAT WILL BE RECEIVING METRICS # # THIS IS OPTIONAL - YOU DON'T NEED IT BY DEFAULT # It only exists to give you finer control of the master settings for each # slave host, when the same API key is used by many netdata slaves / proxies. # # Each netdata has a unique GUID - generated the first time netdata starts. # You can find it at /var/lib/netdata/registry/netdata.public.unique.id # The host sending data will have one. If the host is not ephemeral, # you can give settings for each specific host here. [MACHINE_GUID] # enable this host: yes | no # When disabled, the master will not receive metrics for this host. # THIS IS NOT A SECURITY MECHANISM - AN ATTACKER CAN SET ANY OTHER GUID. # Use only the API key for security. enabled = no # The number of entries in the database history = 3600 # The memory mode of the database: save | map | ram | none memory mode = save # Health / alarms control: yes | no | auto health enabled = yes # postpone alarms when the sender connects postpone alarms on connect seconds = 60 # need to route metrics differently? #proxy enabled = yes | no #proxy destination = IP:PORT IP:PORT ... #proxy api key = API_KEY
