DataBuff v0.1.10 is ready: the notification portal shows real webhook delivery records; oversized MCP tool results no longer blow up the model context; the Doris FE cgroup startup failure is fixed. Versus v0.1.9: 11 commits, no schema migration.
Highlights
- Webhook delivery records:
/notify/recordsnow returns real send records (batch, attempts, status code, duration, primary alert status / description) instead of an empty placeholder. - Oversized MCP result guard: text results above 128 KB are stored in the session workspace; the model receives a preview plus a file path and can read the rest with workspace commands (
APM_AGENT_MCP_TOOL_RESULT_MAX_BYTES). - MCP tool fixes: business-error envelopes and runtime exceptions now report
isError; tool descriptions gained Asia/Shanghai time formats, the default one-hour window, result caps and required-argument contracts. - Doris FE startup fix: Docker / K8s deploy scripts append
-XX:-UseContainerSupportto the FE JVM options (idempotent), fixing the cgroup-aware NPE at startup. - Webhook payloads:
id/occurredAt(source event time) added so standard-event receivers order lifecycle changes correctly. - Service analysis: remote virtual service filtering fixed —
service.remotetargets now follow the serviceId dimension like db/redis/mq. - Dependency security baseline: log4j2 2.25.5, Tomcat 10.1.59, Jackson 2.22.2, Logback 1.5.34, mysql-connector-j 26.7.0, Spring Framework 6.2.19, ZooKeeper 3.9.5 pinned above the BOM defaults.
- Demo fault injection: the demo app gained a fault-injection HTTP server with Kafka change events, and refreshed OTLP / SkyWalking fixtures.
- Docs: alarm rule configuration example added to the alarm manual (GitHub #78).
