[main] # instance_id allows you to run multiple trickster processes on the same host and log to separate files # Useful for baremetal, not so much for elastic deployments, so only uncomment if you really need it #instance_id = 1 # Configuration options for the Proxy Server [proxy_server] # listen_port defines the port on which Trickster's Proxy server listens. # since this is a proxy for Prometheus, we use 9090 by default, just like Prometheus does # listen_port = 9090 # listen_address defines the ip on which Trickster's Proxy server listens. # empty by default, listening on all interfaces # listen_address = [cache] # cache_type defines what kind of cache Trickster uses # options are 'boltdb', 'filesystem', 'memory', and 'redis'. # The default is 'memory'. cache_type = 'memory' # record_ttl_secs defines the relative expiration of cached queries. default is 6 hours (21600 seconds) # record_ttl_secs = 21600 # reap_sleep_ms defines how long the cache reaper waits between reap cycles. Default is 1000 (1s) # reap_sleep_ms = 1000 # compression determines whether the cache should be compressed. default is true # compression = true ### Configuration options when using a Redis Cache # [cache.redis] # protocol defines the protocol for connecting to redis ('unix' or 'tcp') 'tcp' is default # protocol = 'tcp' # endpoint defines the fqdn+port or path to a unix socket file for connecting to redis # default is 'redis:6379' # endpoint = 'redis:6379' ### Configuration options when using a Filesystem Cache # [cache.filesystem] # cache_path defines the directory location under which the Trickster cache will be maintained # default is '/tmp/trickster' # cache_path = '/tmp/trickster' # Configuration options when using a BoltDb Cache #[cache.boltdb] # filename defines the file where the Trickster cache will be maintained # default is 'trickster.db' # filename = 'trickster.db' # bucket defines the name of the BotlDb bucket (similar to a namespace) under which our key value store lives # default is 'trickster' # bucket = 'trickster' # Configuration options for mapping Origin(s) [origins] ### The default origin [origins.default] # origin_url defines the URL of the origin. Default is http://prometheus:9090 origin_url = 'http://prometheus:9090' # timeout_secs defines how many seconds Trickster will wait before aborting and upstream http request. Default: 180s # timeout_secs = 180 # api path defines the path of the Prometheus API (usually '/api/v1') api_path = '/api/v1' # ignore_no_cache_header disables a client's ability to send a no-cache to refresh a cached query. Default is false # ignore_no_cache_header = false # max_value_age_secs defines the maximum age of specific datapoints in seconds. Default is 86400 (24 hours) max_value_age_secs = 86400 # fast_forward_disable, when set to true, will turn off the 'fast forward' feature for any requests proxied to this origin # fast_forward_disable = false # For multi-origin support, origins are named, and the name is the second word of the configuration section name. # In this example, an origin is named "foo". Clients can indicate this origin in their path (http://trickster.example.com:9090/foo/query_range?.....) # there are other ways for clients to indicate which origin to use in a multi-origin setup. See the documentation for more information # [origins.foo] # origin_url = 'http://prometheus-foo:9090' # api_path = '/api/v1' # default_step = 300 # ignore_no_cache_header = false # max_value_age_secs = 86400 # timeout_secs = 180 # Configuration Options for Metrics Instrumentation [metrics] # listen_port defines the port that Trickster's metrics server listens on at /metrics listen_port = 8082 # listen_address defines the ip that Trickster's metrics server listens on at /metrics # empty by default, listening on all interfaces # listen_address = # Configruation Options for Profiler [profiler] # enabled indicates whether to start the profiler server when Trickster starts up. Default: false # enabled = false # listen_port defines the port that Trickster's profiler server listens on at /debug/pprof. Default: 6060 # listen_port = 6060 # Configuration Options for Logging Instrumentation [logging] # log_level defines the verbosity of the logger. Possible values are 'debug', 'info', 'warn', 'error' # default is info log_level = 'info' # log_file defines the file location to store logs. These will be auto-rolled and maintained for you. # not specifying a log_file (this is the default behavior) will print logs to STDOUT log_file = '/var/log/trickster/trickster.log'
