Create a seperate user with read only rights for this particular endpoint - -### Default Behavior - -#### Auto-Detection - -If the Netdata Agent and the Tomcat webserver are in the same host, without configuration, module attempts to connect to http://localhost:8080/manager/status?XML=true, without any credentials. So it will probably fail. - -#### Limits - -This module is not supporting SSL communication. If you want a Netdata Agent to monitor a Tomcat deployment, you shouldnt try to monitor it via public network (public internet). Credentials are passed by Netdata in an unsecure port - -#### Performance Impact - -The default configuration for this integration is not expected to impose a significant performance impact on the system. - - -## Metrics - -Metrics grouped by *scope*. - -The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels. - - - -### Per Tomcat instance - -These metrics refer to the entire monitored application. - -This scope has no labels. - -Metrics: - -| Metric | Dimensions | Unit | -|:------|:----------|:----| -| tomcat.accesses | accesses, errors | requests/s | -| tomcat.bandwidth | sent, received | KiB/s | -| tomcat.processing_time | processing time | seconds | -| tomcat.threads | current, busy | current threads | -| tomcat.jvm | free, eden, survivor, tenured, code cache, compressed, metaspace | MiB | -| tomcat.jvm_eden | used, committed, max | MiB | -| tomcat.jvm_survivor | used, committed, max | MiB | -| tomcat.jvm_tenured | used, committed, max | MiB | - - - -## Alerts - -There are no alerts configured by default for this integration. - - -## Setup - -### Prerequisites - -#### Create a read-only `netdata` user, to monitor the `/status` endpoint. - -This is necessary for configuring the collector. - - -### Configuration - -#### File - -The configuration file name for this integration is `python.d/tomcat.conf`. - - -You can edit the configuration file using the `edit-config` script from the -Netdata [config directory](/docs/netdata-agent/configuration/README.md#the-netdata-config-directory). - -```bash -cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata -sudo ./edit-config python.d/tomcat.conf -``` -#### Options - -There are 2 sections: - -* Global variables -* One or more JOBS that can define multiple different instances to monitor. - -The following options can be defined globally: priority, penalty, autodetection_retry, update_every, but can also be defined per JOB to override the global values.Additionally, the following collapsed table contains all the options that can be configured inside a JOB definition. - -Every configuration JOB starts with a `job_name` value which will appear in the dashboard, unless a `name` parameter is specified. - - -<details open><summary>Config options per job</summary> - -| Name | Description | Default | Required | -|:----|:-----------|:-------|:--------:| -| update_every | Sets the default data collection frequency. | 5 | no | -| priority | Controls the order of charts at the netdata dashboard. | 60000 | no | -| autodetection_retry | Sets the job re-check interval in seconds. | 0 | no | -| penalty | Indicates whether to apply penalty to update_every in case of failures. | yes | no | -| url | The URL of the Tomcat server's status endpoint.
