 # Log load client
 
 This project is a golang application to generate logs and send them to various output destinations in various formats. The app runs as a single executable. If more load is needed, scale the app horizontally.
+
 Example:
 
-```bash
-$ ./logger --command=generate
-goloader seq - localhost.localdomain.0.00000000000000003505C218B3455F5F - 0000000000 - You're screwed !
-goloader seq - localhost.localdomain.0.00000000000000003505C218B3455F5F - 0000000001 - Don’t use beef stew as a computer password. It’s not stroganoff.
-goloader seq - localhost.localdomain.0.00000000000000003505C218B3455F5F - 0000000002 - failed to reach the cloud, try again on a rainy day
-goloader seq - localhost.localdomain.0.00000000000000003505C218B3455F5F - 0000000003 - successfully launched a car in space
-goloader seq - localhost.localdomain.0.00000000000000003505C218B3455F5F - 0000000004 - error while reading floppy disk

+```shell
+$ ./logger
+goloader seq - hostname.example.com - 0000000000 - infinite loop succeeded in less than 3 seconds
+goloader seq - hostname.example.com - 0000000001 - Don’t use beef stew as a computer password. It’s not stroganoff.
+goloader seq - hostname.example.com - 0000000002 - cannot over-write a locked variable.
+goloader seq - hostname.example.com - 0000000003 - failed to get an error message
 ```
 ## Usage
 
-examples using docker image:
-`podman run quay.io/openshift-logging/cluster-logging-load-client:latest generate`  - start outputting logs to stdout
-
-
-examples using local binary:  
-`./logger --command=generate` - start outputting logs to stdout  
-`./logger --command=generate --url=http://localhost:3100/api/prom/push` - send logs to loki  
-`./logger --command=generate --logs-per-second=500` - logs 500 log lines per second (default is one log line per seconds)  
-

-## Build
-
-To build the app run `make build`  
-To build docker image use `make build-image`  
-To push docker image use `make push-image`

-## Elasticsearch
-
-### Generate logs to elasticsearch v6
-
-Logger sends logs to elasticsearch using its `bulk` API.
-Launch an elasticsearch(v6) container:
-```
-    make run-es
-```
-
-Run logger and with remote type  `elasticsearch`: 
-```
-    make run-local-es-generate

+      --logs-per-second int          The rate to generate logs. This rate may not always be achievable. (default 1)
+      --queries-per-minute int       The rate to generate queries. This rate may not always be achievable. (default 1)
+      --query string                 Query to use to get logs from storage.
+      --query-range string           Duration of time period to query for logs (Loki only). (default "1s")
+      --synthetic-payload-size int   Overwrite to control size of synthetic log line. (default 100)
+      --tenant string                Loki tenant ID for writing logs. (default "test")

-## Loki
-
-### Generate logs to loki
 
-Launch a loki container:
-```
-    make run-loki
-```
-

-```
-    make run-local-loki-generate
+## From Source
+
+```shell
+# Build binary ("logger")
+$ make build
+# Default configuration
+$ ./logger
+# Increased log rate
+$ ./logger --logs-per-second=500
+# Push logs directly to Loki
+$ ./logger --destination=loki --uri=http://localhost:3100/loki/api/v1/push
 ```
