Hello, I have installed SkyWalking helm chart 4.7.0 in K8s v1.31.7 with Istio installed v1.25.0 . Under Marketplace, I have enabled 'Service Mesh', 'Kubernetes' and 'Rabbitmq'. I have followed the document as mentioned and configured everything.
Facing following issues and I seek help to rectify it. 1. On skywalking-oap pod, Iam seeing the following error popped up frequently. I haven't edited oal files, I am not sure how to fix it. 2025-03-28 12:06:50,956 org.apache.skywalking.oap.server.receiver.ebpf.provider.handler.ContinuousProfilingServiceHandler 157 [grpc-default-executor-19] WARN [] - query continuous profiling service policies failure org.postgresql.util.PSQLException: ERROR: syntax error at or near ")" Position: 84 at org.postgresql.core.v3.QueryExecutorImpl.receiveErrorResponse(QueryExecutorImpl.java:2676) ~[postgresql-42.4.4.jar:42.4.4] at org.postgresql.core.v3.QueryExecutorImpl.processResults(QueryExecutorImpl.java:2366) ~[postgresql-42.4.4.jar:42.4.4] at org.postgresql.core.v3.QueryExecutorImpl.execute(QueryExecutorImpl.java:356) ~[postgresql-42.4.4.jar:42.4.4] at org.postgresql.jdbc.PgStatement.executeInternal(PgStatement.java:496) ~[postgresql-42.4.4.jar:42.4.4] at org.postgresql.jdbc.PgStatement.execute(PgStatement.java:413) ~[postgresql-42.4.4.jar:42.4.4] at org.postgresql.jdbc.PgPreparedStatement.executeWithFlags(PgPreparedStatement.java:190) ~[postgresql-42.4.4.jar:42.4.4] at org.postgresql.jdbc.PgPreparedStatement.executeQuery(PgPreparedStatement.java:134) ~[postgresql-42.4.4.jar:42.4.4] at com.zaxxer.hikari.pool.ProxyPreparedStatement.executeQuery(ProxyPreparedStatement.java:52) ~[HikariCP-3.1.0.jar:?] at com.zaxxer.hikari.pool.HikariProxyPreparedStatement.executeQuery(HikariProxyPreparedStatement.java) ~[HikariCP-3.1.0.jar:?] at org.apache.skywalking.oap.server.library.client.jdbc.hikaricp.JDBCClient.executeQuery(JDBCClient.java:118) ~[library-client-10.1.0.jar:10.1.0] at org.apache.skywalking.oap.server.storage.plugin.jdbc.common.dao.JDBCContinuousProfilingPolicyDAO.queryPolicies(JDBCContinuousProfilingPolicyDAO.java:81) ~[storage-jdbc-hikaricp-plugin-10.1.0.jar:10.1.0] at org.apache.skywalking.oap.server.receiver.ebpf.provider.handler.ContinuousProfilingServiceHandler.queryPolicies(ContinuousProfilingServiceHandler.java:116) [skywalking-ebpf-receiver-plugin-10.1.0.jar:10.1.0] at org.apache.skywalking.apm.network.ebpf.profiling.v3.ContinuousProfilingServiceGrpc$MethodHandlers.invoke(ContinuousProfilingServiceGrpc.java:302) [apm-network-10.1.0.jar:10.1.0] at io.grpc.stub.ServerCalls$UnaryServerCallHandler$UnaryServerCallListener.onHalfClose(ServerCalls.java:182) [grpc-stub-1.63.0.jar:1.63.0] at io.grpc.internal.ServerCallImpl$ServerStreamListenerImpl.halfClosed(ServerCallImpl.java:356) [grpc-core-1.63.0.jar:1.63.0] at io.grpc.internal.ServerImpl$JumpToApplicationThreadServerStreamListener$1HalfClosed.runInContext(ServerImpl.java:861) [grpc-core-1.63.0.jar:1.63.0] at io.grpc.internal.ContextRunnable.run(ContextRunnable.java:37) [grpc-core-1.63.0.jar:1.63.0] at io.grpc.internal.SerializingExecutor.run(SerializingExecutor.java:133) [grpc-core-1.63.0.jar:1.63.0] at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) [?:?] at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) [?:?] at java.lang.Thread.run(Unknown Source) [?:?] 2. Envoy logs are not getting displayed for the services in dataplane. 3. Namespace and deployment counts are not shown. There are 6 namespaces and many deployments are created in that cluster. 4. In Kubernetes, service section, apart from Overview menu, other menus TCP, HTTP, Topology, Pods, etc. are not displaying any data. Note: There is no error in the open telemetry collector pod. RBAC is set as expected. Regards, Senthilnathan A M
