Trickster 2.0 HTTP Reverse Proxy Cache and Dashboard Accelerator on Ubuntu 24.04 LTS
Azure
Observability
Trickster is a caching reverse proxy and dashboard accelerator that sits in front of your time series database, serving repeat query results from cache so dashboards load fast and the database is asked far less often.
Overview
Trickster is an open source HTTP reverse proxy cache and time series dashboard accelerator. It sits between your dashboards and your time series database, understands the query language of backends such as Prometheus, InfluxDB and ClickHouse, and caches the results of the range queries dashboards make on every refresh. When a panel is reloaded, Trickster serves the part of the time range it already holds from cache and asks the database only for the newly elapsed slice, rather than re fetching the whole window. It also collapses concurrent identical requests into a single origin fetch, so a wall of dashboards opening at once no longer stampedes the database. The result is dashboards that render noticeably faster and a time series backend under far less repetitive load, with no change to the dashboards or to the database itself.
Why the cloudimg image
cloudimg ships Trickster with a Prometheus already installed alongside it on the same instance and wired up as the default origin, so the appliance answers real queries the moment first boot finishes rather than waiting for you to supply a database, and repointing it at your own upstream is a single line of configuration. It is secure by default: the accelerated query port is protected by HTTP Basic authentication using a credential generated uniquely on each instance at first boot and stored in a root only file, so no password is ever baked into the image or shared between customers, and the proxy refuses to start at all until that credential exists. The metrics endpoint, the management endpoint that prints the running configuration, and the bundled Prometheus are all bound to the loopback interface so nothing sensitive is exposed to the internet. The base is fully patched with unattended security upgrades enabled, and every deployment is paired with a step by step deploy guide, backed by 24/7 cloudimg support.
Common uses
- Speed up Grafana dashboards that repeatedly query the same time ranges
- Cut repetitive query load on a Prometheus, InfluxDB or ClickHouse backend
- Collapse simultaneous identical dashboard requests into one origin fetch
