stardog-admin server metrics
Description
Retrieves server metrics
Usage
stardog-admin [ --krb5 ] [ --krb5-disable-rdns ] [ --server <server url> ] server metrics [ --locks ] [ --no-databases ] [ {-p | --passwd} <password> ] [ {-P | --ask-password} ] [ --run-as <username> ] [ --samples ] [ --threads ] [ {-u | --username} <username> ] [ {-v | --verbose} ] [--] <space-separated metric name regex patterns> (see command examples)
Options
| Name, shorthand | Description |
|---|---|
--krb5 | Use the Kerberos environment. |
--krb5-disable-rdns | Disable reverse DNS lookup for Kerberos clients. |
--locks | locked monitors and locked synchronizers in the thread dump. Takes effect only if –threads is provided. |
--no-databases | Do not include database-specific metrics and instead only return server-wide metrics. By defaultdatabase details will be shown. |
-p <password>, --passwd <password> | Password. |
-P, --ask-password | Prompt for password. |
--run-as <username> | User to impersonate when running the command |
--samples | Include detailed sample information for each meter and histogram. |
--server <server url> | URL of Stardog Server. If this option isn’t specified, it will be read from JVM argument ‘stardog.default.cli.server’. If the JVM arg isn’t set, the default value ‘http://localhost:5820’ is used. If server URL has no explicit port value, the default port value ‘5820’ is used. Example: ‘stardog-admin –server http://12.34.56.78:5820 server stop’ |
--threads | Include the thread dump from the server. |
-u <username>, --username <username> | User name. |
-v, --verbose | Flag that can cause more detailed information to be printed such as errors and status. Exact output depends upon the command and options used. |
-- | This option can be used to separate command-line options from the list of argument(s). (Useful when an argument might be mistaken for a command-line option) |
<space-separated metric name regex patterns> (see command examples) | Display only metrics, matching the specified patterns. |
Discussion
Reports server metrics. Metrics are organized using a dot-delimited namespace system. Top-level namespaces include: admin.threads (thread management for admin HTTP operations), com.stardog.http.server.
Examples
Display all metrics:
$ stardog-admin server metrics
Display dbms.credentials.cache.size metric:
$ stardog-admin server metrics dbms.credentials.cache.size
Display dbms.credentials.cache.size metric and metrics matching the pattern dbms.mem.*:
$ stardog-admin server metrics dbms.credentials.cache.size "dbms.mem.*"
Display metrics matching dbms.mem.* and dbms.memory.*:
$ stardog-admin server metrics "dbms.mem.*" "dbms.memory.*"
Get the thread dump from the server:
$ stardog-admin server metrics --threads "jvm.threads"
