Below are the prospector specific configurations - paths : - /var/log/nginx/*.log input_type : log # You usually want tail_files: true. # Exhaustive example: # Docs: filebeat : prospectors : # Each - is a prospector. In that case, if the proxy installer detects that java v8, 9, 10 or, 11 already exists in the users path that version of Java is used.
How you run the proxy in test mode depends on whether you’re using the JVM bundled with the Wavefront proxy. To test grok patterns before sending data, you can run the proxy in test mode where it reads lines from stdin and prints the generated metric when there is a match with a pattern in logsIngestionConfig.yaml. Testing Grok Patterns in Interactive Mode The Wavefront proxy javadoc contains advanced grok examples.If you want to capture a number inside brackets, you need '\' or "\\" (for the above bullet). Remember that grok patterns expand to regex patterns.YAML parsers escape sequences inside double quotes, which is usually not what you want (e.g. As in the examples above, use single quotes unless you need double quotes.Try your grok pattern with a sample log line in one of the grok parsing debugger tools (e.g. Bugs in grok patterns can be frustrating to debug.The Wavefront proxy includes these patterns and you can always add more. Therefore, the resulting metric would be: myOperationDuration 42 source= You can use this timestamp to match the message for ingestion, but Tanzu Observability always ingests the resulting metric at the time the Wavefront proxy sees the log, not at the time the message was logged in your system. In the example above, the log message has a timestamp. INFO 1476925272 my operation took 42 seconds (and other info here) Each macro can consist of sub-macros, and each macro can bind a substring to a label. You can think of a grok pattern as a regexe with macros. See Dropwizard documentation for details. There are three supported modes of aggregation: counters, gauges, and histograms. Through valueLabel, you can specify which part of the log line contains the metrics to send. Log lines are given structure with java-grok, which is the syntax for the Logstash grok plugin. This configuration file is parsed as a POJO see the javadoc for more details on each field.
In your Wavefront proxy configuration file, add these new entries:ĪggregationIntervalSeconds : 5 # Metrics are aggregated and sent at this interval counters : - pattern : ' % seconds' metricName : ' myOperationDuration' valueLabel : ' duration' Configuring the Wavefront Proxy to Listen for Log Data
#FILEBEATS SET DOCUMENT ID HOW TO#
The example is merely a starting point- so you understand how to ingest metrics from any log format.
In this example, we configure Tanzu Observability to parse Combined Apache Logs, which is a common logging format for many web services (for example, NGiNX).
