Abstract This memo defines an experimental portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it describes a basic set of managed objects for fault, configuration and performance management of applications from a systems perspective. More specifically, the managed objects are restricted to information that can be determined from the system itself and which does not require special instrumentation within the applications to make the information available. This memo does not specify a standard for the Internet community. 2. The SNMPv2 Network Management Framework The SNMPv2 Network Management Framework consists of four major components. They are: o STD 17, RFC 1213 [1] defines MIB-II, the core set of managed objects for the Internet suite of protocols. o RFC 1902 Structure of Management Information for Version 2 of the Simple Network Management Protocol (SNMPv2) o RFC 1903 Textual Conventions for Version 2 of the Simple Network Management Protocol (SNMPv2) o RFC 1904 Conformance Statements for Version 2 of the Simple Network Management Protocol (SNMPv2) o RFC 1905 Protocol Operations for Version 2 of the Simple Network Management Protocol (SNMPv2) o RFC 1906 Transport Mappings for Version 2 of the Simple Network Management Protocol (SNMPv2) o RFC 1907 Management Information Base for Version 2 of the Simple Network Management Protocol (SNMPv2) Expires March 10, 1997 [Page 3] Internet Draft System Application MIB Sept. 10, 1996 o RFC 1908 Coexistence between Version 1 and Version 2 of the Internet-standard Network Management Framework The Framework permits new objects to be defined for the purpose of experimentation and evaluation. 2.1. Object Definitions Managed objects are accessed via a virtual information store, termed the Management Information Base or MIB. Objects in the MIB are defined using the subset of Abstract Syntax Notation One (ASN.1) defined in the SMI[1]. In particular, each object type is named by an OBJECT IDENTIFIER, an administratively assigned name. The object type together with an object instance serves to uniquely identify a specific instantiation of the object. For human convenience, we often use a textual string, termed the object descriptor, to refer to the object type. Expires March 10, 1997 [Page 4] Internet Draft System Application MIB Sept. 10, 1996 3. Overview The primary purpose of computing technologies is the execution of application software. These applications, typically specialized collections of executables, files, and interprocess communications, exist to solve business, scientific or other "problems". The configuration, fault detection, performance monitoring and control of application software across it's life on a host computer is of great economic importance. For the purposes of our work, we define applications as one or more units of executable code and other resources, installed on a single host system that a manager may think of as a single object for management purposes. The information described by the objects in the System Application MIB support configuration, fault, and performance management; they represent some of the basic attributes of application software from a systems (non-application specific) perspective. The information allows for the description of applications as collections of executables and files installed and executing on a host computer. This draft is concerned primarily with, and defines a model for, application information resident on a host computer which can be determined from the system itself, and not from the individual applications. This system-level view of applications is designed to provide information about software applications installed and running on the host system without requiring modifications and code additions to the applications themselves. This approach was taken to insure ease and speed of implementation, while allowing room for future growth. We believe that this work will be immediately followed by work on a separate MIB module that will provide an application- level view of a single application. This new "appl MIB" will define a common set of attributes that pertains to a generic application, but which requires instrumentation (and therefor modification) to the application software itself in order to be implemented. Expires March 10, 1997 [Page 5] Internet Draft System Application MIB Sept. 10, 1996 4. Architecture for Application Management In the area of application management it is fully acknowledged and even expected that additional MIB modules will be defined over time to provide even greater level of detail regarding applications. This MIB module presents the most general case: a set of management objects relating to generic applications whose object values can be determined from the computer system itself and do not require instrumentation within the application. A finer grained level of detail is planned for the future "appl MIB" which will be a common set of management objects relating to generic applications, but which require some type of instrumentation in the application in order to be determined. Since this new MIB module will provide a finer level of detail, any connection to the sysAppl MIB should be made by having pointers from this more detailed MIB back to the more generic sysAppl MIB. Likewise, as application- specific MIB modules such as the HTTP MIB, etc., are developed over time, these more specific MIBs should reference back to the more generic MIBs. In all cases of MIB design, it is recommended that when chosing the index for a table, the arbitrary small integer index should be passed over in favor of a more meaningful, derivable value whenever possible. A derivable value makes it easier for a separately implemented MIB module (possibly on a different sub-agent) to match the table index for a table in another MIB. While this MIB module does not attempt to provide every detailed piece of information for managing applications, it does provide a basic systems-level view of the applications and their components on a single host system. Expires March 10, 1997 [Page 6] Internet Draft System Application MIB Sept. 10, 1996 5. The Structure of the MIB The System Application MIB structure models application packages as a whole, and also models the individual elements (files and executables) which collectively form an application. The MIB is structured to model information regarding installed application packages and the elements which make up each application package. The MIB also models activity information on applications (and in turn, their components) that are running or have previously run on the host system. In modelling applications and their elements, this MIB module provides the necessary link for associating executing processes with the applications of which they are a part. The objects are arranged into the following groups: - System Application Installed Group - sysApplInstallPkgTable - sysApplInstallElmtTable - System Application Run Group - sysApplRunTable - sysApplPastRunTable - sysApplElmtRunTable - sysApplElmtPastRunTable - (scalars for restricting table sizes) As can be seen by the arrangement above, for each category, the MIB first treats an application package as a whole, and then breaks down the package to provide information about each of the elements (executable and non-executable files) of the package. 5.1. System Application Installed Group The System Application Installed group consists of two tables. Through these two tables, administrators will be able to determine which applications have been installed on a system and what their constituent components are. The first table, the sysApplInstallPkgTable, lists the application packages installed on a particular host. The second, the sysApplInstallElmtTable, provides information regarding the Expires March 10, 1997 [Page 7] Internet Draft System Application MIB Sept. 10, 1996 executables and non executable files, or elements, which collectively compose an application. This information is discoverable provided that certain conventions are followed by administrators during the installation of host application software. NOTE: This MIB is intended to work with applications that have been installed on a particular host, where "installed" means that the existence of the application and the association between an application and its component files can be discovered without requiring additional instrumentation of the application itself. 5.2. System Application Run Group This group models activity information for applications that have been invoked and are either currently running, or have previously run, on the host system. Likewise, the individual elements of an invoked application are also modeled to show currently running processes, and processes that have run in the past. This information is modeled using two pairs of tables: a pair of tables for the application run and past run, and a pair for the elements running and past run. Seven scalars are also defined to control the size of the past run tables. 5.2.1. sysApplRunTable and sysApplPastRunTable The sysApplRunTable and the sysApplPastRunTable make up the first pair of tables. The sysApplRunTable contains the application instances which are currently running on the host. Each time an application is invoked, a new entry is created in the sysApplRunTable to provide information about that particular invocation of the application. An entry will remain in this table until the application instance terminates, at which time the entry will be deleted from the sysApplRunTable and placed in the sysApplPastRunTable. The sysApplPastRunTable maintains a history of instances of applications which have previously executed on the host. Entries to this table are made when an invoked application from the sysApplRunTable has terminated; the table entry which Expires March 10, 1997 [Page 8] Internet Draft System Application MIB Sept. 10, 1996 represents the application instance is removed from the SysApplRunTable and is added to the sysApplPastRunTable. Because the sysApplPastRunTable will continuously grow as applications are executed and terminate, two scalars are defined to control the ageing-out of table entries. The value of sysApplPastRunMaxRows specifies the maximum number of entries the table may contain, whilst the sysApplPastRunTblTimeLimit specifies the maximum age of the table entries. Oldest entries are removed first. It is important to note that the sysApplRunTable and sysApplPastRunTable contain entries for each INVOCATION of an application. A single application package might be invoked multiple times by different users; each invocation is properly recorded by a separate entry in the sysApplRunTable. 5.2.2. sysApplElmtRunTable and sysApplElmtPastRunTable While the sysApplRunTable and sysApplPastRunTable focussed on applications as a whole, the sysApplElmtRunTable and sysApplElmtPastRunTable provide information regarding an application's executable elements, (processes), which are either currently executing or have executed in the past. The sysApplElmtRunTable contains an entry for every process currently running on the host. An entry is created in this table for each instance of a process at the time it is started, and will remain in the table until the process terminates. Note that in order to provide complete information on load on the system, this table lists EVERY running process, not just those processes that are running as part of an identified application. However, when processes terminate, only those entries which are part of an identified application are moved to the sysApplElmtPastRunTable. The sysApplElmtPastRunTable maintains a history of instances of processes which have previously executed on the host as part of an application. When a process from the sysApplElmtRunTable terminates, the entry is moved to this sysApplElmtPastRunTable provided that the process was part of Expires March 10, 1997 [Page 9] Internet Draft System Application MIB Sept. 10, 1996 an identified application. If the process cannot be associated to any 'parent' application, than it is simply removed from the sysApplElmtRunTable. This allows for processes like 'ps' or 'grep' to show up in the Running table, (where they are consuming resources and are thus, "interesting"), but not in the Past Run table. Because the sysApplElmtPastRunTable will continuously grow as processes are executed and terminate, two scalars are defined to control the ageing-out of table entries. The value of sysApplElmtPastRunMaxRows specifies the maximum number of entries the table may contain, whilst the sysApplElmtPastRunTblTimeLimit specifies the maximum age of the table entries. Oldest entries are removed first. Expires March 10, 1997 [Page 10] Internet Draft System Application MIB Sept. 10, 1996 6.

Security Considerations In order to implement this MIB, an agent must make certain management information available about various logical and physical entities within a managed system, which may be considered sensitive in some network environments. Therefore, a network administrator may wish to employ instance-level access control, and configure the Entity MIB access (i.e., community strings in SNMPv1 and SNMPv2C), such that certain instances within this MIB (e.g., entLogicalCommunity, or entire entLogicalEntries, entPhysicalEntries, and associated mapping table entries), are excluded from particular MIB views. 8.
