UP
UP is a simple client for testing Prometheus remote-write and Loki write requests.
For a specified metric the client writes the metric at a chosen interval, where the value of the metric is always the current timestamp in milliseconds.
It can also read the metric back from a specified endpoint and compare its value against the current time to determine the total write-read latency.
For a specified log entry the client writes the log entry at a chosen interval for the value given.
It can also read the log back from a specified endpoint and compare the number of results.
When the given duration is greater than 0s, UP will evaluate number of errors and will exit with a non-zero code if the ratio is greater than the specified threshold.
Getting Started
The easiest way to begin making remote write requests is to run the UP container.
For example, to report an up metric every 10 seconds, run:
docker run --rm -p 8080:8080 quay.io/observatorium/up --endpoint-write=https://example.com/api/v1/receive --period=10sNote that the metric name and labels are customizable.
For example, to report a metric named foo with a custom bar label, run:
docker run --rm -p 8080:8080 quay.io/observatorium/up --endpoint-write=https://example.com/api/v1/receive --period=10s --name foo --labels 'bar="baz"'Usage
Usage of ./up:
-duration duration
The duration of the up command to run until it stops. If 0 it will not stop until the process is terminated. (default 5m0s)
-endpoint-read string
The endpoint to which to make query requests.
-endpoint-type string
The endpoint type. Options: 'logs', 'metrics'. (default "metrics")
-endpoint-write string
The endpoint to which to make remote-write requests.
-initial-query-delay duration
The time to wait before executing the first query. (default 10s)
-labels value
The labels in addition to '__name__' that should be applied to remote-write requests.
-latency duration
The maximum allowable latency between writing and reading. (default 15s)
-listen string
The address on which internal server runs. (default ":8080")
-log.level string
The log filtering level. Options: 'error', 'warn', 'info', 'debug'. (default "info")
-logs value
The logs that should be sent to remote-write requests.
-logs-file string
A file containing logs to send against the logs write endpoint.
-name string
The name of the metric to send in remote-write requests. (default "up")
-period duration
The time to wait between remote-write requests. (default 5s)
-queries-file string
A file containing queries to run against the read endpoint.
-step duration
Default step duration for range queries. Can be overridden if step is set in query spec. (default 5m0s)
-tenant string
Tenant ID to used to determine tenant for write requests.
-tenant-header string
Name of HTTP header used to determine tenant for write requests. (default "tenant_id")
-threshold float
The percentage of successful requests needed to succeed overall. 0 - 1. (default 0.9)
-tls-ca-file string
File containing the TLS CA to use against servers for verification. If no CA is specified, there won't be any verification.
-tls-client-cert-file string
File containing the default x509 Certificate for HTTPS. Leave blank to disable TLS.
-tls-client-private-key-file string
File containing the default x509 private key matching --tls-cert-file. Leave blank to disable TLS.
-token string
The bearer token to set in the authorization header on requests. Takes predence over --token-file if set.
-token-file string
The file from which to read a bearer token to set in the authorization header on requests.
