3 3 ICCS 2006 (GSRM'06) JIMS Extensions for Resource Monitoring and Management of Solaris 10 Java Management Extensions Java Management Extensions (JMX) technology is a general framework for distributed resource management It offers a general architecture suitable for construction of monitoring systems and management applications written in Java Managed resources are represented as Managed Beans (MBeans), the simple Java objects installed in MBean Server Instrum entation Layer Server L ayer D istrib uted Services L ayer O bject 1 M Bean O bject 2 M Bean Instrum entation Layer M Beans M BeanServer services Service 1 M Bean Service 2 M Bean M BeanServer Connector 1 Connector 2 (HTT P, R M I) Protocol Adaptor (HTM L, SNM P) JM X client Proxy M B eans: - O bject 1 - O bject 2 M B S C onnection protocol enabled client, web browser, etc. M B eanserver Java Virtual M ach ine C lient Java Virtual M achine Provides many ready-to-use services MLet (dynamic modules downloading) Notification Discovery services

4 4 ICCS 2006 (GSRM'06) JIMS Extensions for Resource Monitoring and Management of Solaris 10 JIMS Overview JIMS = JMX based Infrastructure Monitoring System Current implementation supports both Linux and Solaris platforms monitoring and management Client Application Layer consists of applications connected to the JIMS system, which are consumers of the information produced by the system. Client Applications Layer JIMS Clients Visualization, Monitoring Integration Layer enables discovery of all accessible clusters and provides an overall view of the Grid using Global Discovery mechanism. Interoperability Layer provides a common point of communication with Computational Nodes (also called Worker Nodes or WNs) in clusters through dedicated access nodes ( Node - AN). Integration Layer Interoperability Layer Instrumentation Layer JIMS Gateway Node Global Discovery JIMS Gateway Node Instrumentation Layer provides infrastructure and Java application monitoring information using specially-designed sensors & effectors modules installed in the JIMS Monitoring Agent (JIMS M.A.). Computational Node 1 Cluster A JIMS M.A. CPU,Mem,Network, Processes, SGE JIMS M.A. CPU,Mem, Network Processes Computational Node N JIMS M.A. JVM 5.0 Computational Node 1 Cluster B JIMS M.A. J2EE AS Computational Node 2

6 6 ICCS 2006 (GSRM'06) JIMS Extensions for Resource Monitoring and Management of Solaris 10 Solaris 10 Features Zone virtual isolated operating system instance (owning IP addresses, booting capabilities, filesystem) 1 OS instance = 1 global and N local Zones Solaris Container = Zone + Resource Controls Resource Controls; per-process resource limits extended to the Zone, Project and Tasks entities: Project provides a network-wide administrative identifier for related work Task collects a group of processes into a manageable entity that represents a workload component Dynamic Resource Pools; used for dynamic adjusting machine resources Resource Controls Examples: zone.cpu-shares, zone.max-lwps project.cpu-shares, project.max-lwps, project.max-cpu-time task.max-lwps, task.max-cpu-time process.max-cpu-time, process.max-data-size, process.max-address-space Each resource control may have limit specified and reaction to exceeding that limit: denying consumption request sending signal to process or log event no action (useful for monitoring and logging) Extended Accounting logs historical resource usage data (zones, projects, tasks)

8 8 ICCS 2006 (GSRM'06) JIMS Extensions for Resource Monitoring and Management of Solaris 10 JIMS Extension for Solaris 10 - Requirements Reading administrative information about Solaris 10 entities (zones, projects) and performing administrative operations Provide real-time information about resource usage of zones and projects, allow to set limits using resource controls Extract Extended Accounting data and store it in central database Operating within global or local zone (adaptation to environment i.e. detect whether it s running in global or local zone and adjust expose interface) Notifying interested parties about changes in the system (changes of entities and resource usage)

9 9 ICCS 2006 (GSRM'06) JIMS Extensions for Resource Monitoring and Management of Solaris 10 JIMS Extension for Solaris 10 - Design MBeans enable reading and changing properties of zones and projects (i.e. resource controls, member users etc.) and also operations that change zone state MBeans use various s to interact with the OS to collect information about zones and projects; read configuration files or use JNI. Changes in configuration are applied by executing shell scripts and system commands MBeans are able also to emit JMX notifications to inform interested parties about changes in the system (e.g. changed resource usage) Multiple access protocols Uniform management interface Common access interface s RMI Connector HTTP Connector SNMPAdaptor JIMS abstractions - MBeans Solaris 10 access adaptation layer JNI + C API Runtime.exec + CLI config file, logs Java / JIMS Solaris 10 JIMS module Diverse interfaces Real-time resource usage (/proc) Extended Accounting (libexacct) Zones / projects management & Resource Controls commands Zones/projects config files /var/adm/messages Virtualized resources Zone 1 Project Project 1 2 Solaris 10 Global Zone Zone 2 Project Project 1 2 Zone 3 Project Project 1 2 Solaris 10
