+# Script Exporter
+
+GitHub: https://github.com/adhocteam/script_exporter
+
+Prometheus exporter written to execute and collect metrics on script exit status
+and duration. Designed to allow the execution of probes where support for the
+probe type wasn't easily configured with the Prometheus blackbox exporter.
+
+## Sample Configuration
+
+```yaml
+scripts:
+  - name: success
+    script: sleep 5
+
+  - name: failure
+    script: sleep 2 && exit 1
+
+  - name: timeout
+    script: sleep 5
+    timeout: 1
+```
+
+## Running
+
+You can run via docker with:
+
+```
+docker run -d -p 9172:9172 --name script-exporter \
+  -v `pwd`/config.yml:/etc/script-exporter/config.yml:ro \
+  -config.file=/etc/script-exporter/config.yml
+  -web.listen-address=":9172" \
+  -web.telemetry-path="/metrics" \
+  -config.shell="/bin/sh" \
+  adhocteam/script-exporter:master
+```
+
+You'll need to customize the docker image or use the binary on the host system
+to install tools such as curl for certain scenarios.
+
+## Output
+
+`$ curl http://localhost:9172/metrics`
+
+```

+
+## Design
+
+The script exporter adds `script_failure_duration_seconds` and
+`script_duration_seconds` histograms configured with the default buckets
+to the default prometheus handler metrics available at `/metrics`. When Prometheus
+scrapes the target all scripts are executed with sh and the observations are
+included in the output.
+
+YMMV if you're attempting to execute a large number of scripts, and you'd be
+better off creating an exporter that can handle your protocol without launching
+shell processes for each scrape.
