How do I monitor a Zulu JRE?
[note: this is migrated content from an archived forum]
Monitoring of Zulu JREs doesn’t work with some some tools. Why?
Zulu builds are generally ‘visible’ to monitoring tools by default. When you are using a JRE-only Zulu build, whether an eval or a production image, monitoring tools may be invisible. This is due to -XX:-UsePerfData flag is off by default for JRE-only builds.
To resolve this issue, please run the target JRE with -XX:+UsePerfData which will enable monitoring tools to ‘see’ the Java instance.
