esp - Embedded Support Partner
As shipped in IRIX 6.5.22. Added in IRIX 6.5.15.
NAME esp - Embedded Support Partner DESCRIPTION esp is an infrastructure that is integrated into the operating system for the purposes of support. This infrastructure contains various components that perform the following: Capture and store system level events Capture and store system configuration Capture and store system availability information Provide Electronic Logbook for Activities performed Provide features of proactive notification Generate various reports for supportability Log call to ESP Database at The Embedded Support Partner consists of a set of daemons that perform various monitoring activities. These include an event monitoring and management daemon(eventmond) and database daemon(espdbd). By default, esp start at boot time on the system unless it's chkconfig(1M) off. The Embedded Support Partner can be pre-programmed for event monitoring and provides flexible throttling features for the events. Actions can also be programmed for each event. Event sources include kernel, performance monitoring tools, availability tools, configuration monitoring tools and user applications. Events are categorized into classes and types. A class can have many types. Example of a class could be SCSI and the various types under this class could be SCSI hard error, SCSI Bus reset, etc. The event types are uniquely sequenced with pre-assigned numbers. The events propagate to the Embedded Support Partner through syslogd and captured by the eventmond. The message string contains the unique sequence number with a special tag which eventmond identifies. The tag and sequence number also show up in SYSLOG. An example of the message in SYSLOG is: May 24 23:16:34 6D:starwars esphttpd[5722]: |$(0x200120)started User defined events can be added using the Embedded Support Partner user interface. The sequence numbers are automatically generated. User applications can log user defined events into the Embedded Support Partner framework by two mechanisms. Applications can include the EventMonAPI(3X) calls within or could use the command line driven application esplogger(1M). Both methods would need to use the unique sequence number generated by the Embedded Support Partner user interface. The Embedded Support Partner also provides the facility of an electronic log book for logging various activities performed on the system. The capability of a logbook has been provided through the graphical user interface. Entries upto 4K can be made using the logbook capability. A set of reports are available to view the logbook entries between any given dates. The logbook entries are also cross referenced by the event reports on a date basis. This allows a user to check if any log entries are made against events. For those who want to use a non-GUI interface, logbook entries can be added using esplognote(1) and viewed using the espreport(1) command, ie. "espreport logbook". Each event can have associated actions that can be proactively triggered by the Embedded Support Partner in reaction to an event. Actions can be pre-programmed and assigned to events. Examples of actions include: Graphical posts onto the console, email, chatty paging and numeric paging. Most of the notification features are incorporated using espnotify(1) utility. Numeric paging needs the use of modems and uses QuickPage(1M) software. The option of numeric paging must be chkconfig(1M) on for use. The Embedded Support Partner also provides the facility to manage multiple systems in a group environment. Under this environment, one of the systems can be designated as the Group Manager. The Group Manager can then subscribe to various events from the member systems. The member systems forward the occurrance and associated data of the subscribed events to the Group Manager for which proactive actions can be set to be taken. Certain class of events have to be subscribed in full. Examples of this are Availability, Configuration, etc. The Group Manager also provides the capability to monitor various services on the member systems. These include: icmp, rpcbind, dns, smtp, nntp, etc. The services can be configured using the Embedded Support Partner user interface and requires that pcp_eoe subsystem be installed. The Group Manager capabilities are licensed. The Embedded Support Partner supports a html browser based interface and for non-graphics systems, a command-line interface called espconfig(1). The browser interface supports both single systems and multiple systems (Group Management) environment. At the time of logging in, one must choose the type from the user interface. The interfaces runs from a http based server that is started by inetd on connection only. Access to the esphttpd server is driven by IP address filtering. If the address is not found in the list of valid IP address configured by the ESP administrator, the access is denied. Also, if the IP address do not resolve back to a hostname, access is also denied unless 'ReverseDNSLookup: off's set in /etc/esphttpd.conf configuration file. Note: If your web browser uses a proxy-server, you must add IP address of this proxy-server to the "Allow Access" list, because the connection in this case will be indirect. The Embedded Support Partner supports a variety of reports. These include: hardware and software reports, event reports, actions reports and availability reports. A printable view icon is provided against all the reports. Clicking the icon will generate a plain text output to the browser. The browser print capability can be used to print to paper. All reports are formatted to fit in 80 columns. The same command-line functionality is offered in espreport(1). The Embedded Support Partner user interface, by default, is accessible by localhost only. The user interface can be started by the launchESPartner(1) or by clicking the icon for Embedded Support Partner in the icon catalog under the support tools page. The Embedded Support Partner could then be customized according to the needs at the site. An online help facility is also provided for reference. The Embedded Support Partner may also send ESP events to a centralized database at SGI. An application (espcall) has been introduced that gets automatically triggered against events if ESP has been configured to send data back to SGI. The application supports both text and compressed,encrypted, encoded formats. The format is also selectable both in the UI and command line applications. Information transmitted back to SGI depends on the type of event. Information includes customer contact information, event information, hardware and software installed, crash analysis and syslog information. The analysis report and syslog messages are sent only if the system panic'd. Information is mailed out to esp@sgi.com. Optional mail addresses can be entered to receive copies of what is mailed to esp@sgi.com . SECURITY Considerations In order to reduce potential security breaches that ESP may cause, SGI asked RSA Security, Inc. to perform an evaluation of ESP. Pursuant to the evaluation, SGI implemented a wide range of recommendations from RSA Security, including: o Validating user permissions of process for proactive actions and disabling actions by root o Implementing reverse DNS lookup for both the Web server and ESP SGM o HMAC/MD5 digital signature of all data transfers to the ESP SGM o Disabling of login attempts with time-out periods o Implementing a CLI for all ESP configuration/reports, disabling the use of the ESP Web server o Restricting all ESP database transactions locally NOTE:If there are security issues, please contact your customer support representative or send Email to security-alert@sgi.com. CAVEATS o If esp is chkconfig off while it's running, eventmond will still log events in the database and action scripts will still be executed. However, espconfig(1) and esphttpd won't perform any action. To ensure that esp is off, please execute '/etc/init.d/esp stop' or reboot the system. o To restart esp , execute '/etc/init.d/esp start'. o If new hardware and/or new software is introduced while the system is running, esp will recognized new, updated or deleted items by executing '/usr/sbin/configmon -u'. o Changes to /etc/eshttpd.conf configuration file require a 'killall esphttpd'. o If your web browser uses a proxy-server, you must add IP address of this proxy-server to the "Allow Access" list, because the connection in this case will be indirect. o Not the entire list of feature of availmon(5) are configurable in ESP. In particular, autoemail, autoemail.list features need to be configured using amconfig(1M) command-line interface.
