+[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

+
+    # 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

+    # 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

+# 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'
