Abo ut T his Doc ument This document presents procedural and example information to help you become familiar Application Discovery , how to manipulate the data presentation, and how to manage event notification. It will help you understand how Application Discov ery can be useful to you.
R elated Inf ormati on The following documents and resources contain useful additional information. • HP WBEM Solutions : http://h71028.www7.hp.com/enterprise/9920-0-0-225-121.html?jumpid=reg_R1002_USEN • PCRE - Perl Compatible Regular Expressions at http://www .
1 Intr odu cti on HP Application Discov ery works from within HP Systems Insight Manager (HP SIM) to give you the ability to inv entory running and installed applications across your system netw ork and to centrally monitor application activity .
14.
2 C omponen ts and C oncepts Appli cation Dis cov ery Com ponents Application Discovery contains these components: • The Application Discovery agent , which discov ers the presence of applications a.
NO TE: An application inventory in a data center or enterprise setting is sensitive material. Therefore, all communication paths in Application Discovery are encrypted and authenticated to check for proper user authorization. See VSE Management Software V ersion 4.
Figur e 2- 1 Segment of Proces s Inv entory Data For example, if the discov ery ratio is low , the number of processes that HP Application Discovery is matching to templates is low .
• Install an HP Application Discovery agent in order to monitor processes and applications on that host. See VSE Management Software V ersion 4.0 Installation and Update Guide for HP-UX for instructions. • Start an agent on a system where the agent is installed, but not running.
On HP -UX: Supplied templates are stored in /var/opt/amgr/templates/amgr/ to make it easier to update templates with new releases of HP Application Discovery .
On the AD Server tab screen, you can see a graphic display of Application Discovery memory consumption plotted against discovery data for processes and packages.
3 Pr ocedur e s W ith Application Discovery , you can perform the following tasks: • Check the progress of discovery . • Define an application for discovery . • Modify the behavior of agents running on managed systems. • Set attributes that determine what events to display , where to display them, and the priority they should have.
Using HP S IM to Stop the AD Age nt 1. Initiate this task by selecting Configure → Configure VSE Agents → Stop AD Ag ents from the HP SIM top menu bar . 2. Using the HP SIM system list, select the HP-UX systems where y ou want to stop an agent. Click Apply .
6. If desired, scroll down to access a printable copy of the report. Click the Vie w Printable Report button to open the printable version of the report.
Adj usting the U ser In terf ace Y ou can alter several visual and behavioral aspects of the Application Discov ery user interface for the duration of your user session. Application Discov ery does not store these changes as user preferences. T o take adv antage of these settings, select the following tabs: Admin/Config , then UI .
Set Number o f T able Ro w s T o help y ou to view manageable chunks of data, you can select the maximum number of rows to display within an Application Discovery table. Application Discov ery apportions the data into separate pages based on the number that you select.
NO TE: Hidden applications. Note that the filtering discussed in this section concerns manipulating data that is currently displayed in the tables. Some applications are not shown in the table. They might be common, low-level processes that are hidden by default, or they might have been hidden by a user .
2. In the table listing all hosts, find the column labeled 'V isible'. 3. Click the button to toggle visibility of hosts on Application Discov ery screens to yes ( Y ) or no ( N ). Select N to prevent the host and its accompanying data from showing in Application Discovery data tables.
Modify ing the Maxim um Si z e of an E v ent L ist T o set ev ent list size, do the following steps. 1. Click the Admin/Config tab, then the AD Server tab. 2. Locate the drop-down 'Max Ev ents' listed at the bottom of the "Serv er Configuration" box to the left of the graph.
Setting E ven t Attr ibutes Intr oducti on to Ev ent S ettings in Appli cation Disco v er y Application Discovery logs v arious application and administrative ev ents occurring in the computing network. It records ev ents that occur in association with applications, host machines, agents, and templates.
2. Select the location desired for each ev ent type. The default setting is "Show in AD", meaning show this event type in the Application Discovery event tables only . Use "Send to SIM" to show the event type in HP Systems Insight Manager event tables as well as Application Discovery ev ent tables.
NO TE: HP supplies a default set of application templates with Application Discov ery . Editing one of these templates does not actually change the original template.
NO TE: My application does not appear in the "Applications affected..." table. Why? There are several possible explanations for this to occur: • It takes some time for template matching to complete. Action: W ait a couple of minutes to see whether or not matching occurs.
Constructing Regular Expres sions: HP Application Discovery recognizes regular expressions constructed using P erl 5 or POSIX syntax and semantics. T o learn more, consult PCRE - Perl Compatible Regular Expressions at http://www .
Summary F ields and T heir Desc ripti ons The following figure shows the Summary portion of an application template. Fields and their descriptions follow the image. Description Field Required. Unique name given to the template to represent the application.
Description Field By default during initial discovery , HP Application Discovery sets objects recognized as packages to "no" and objects recognized as templates to "yes".
NO TE: If you w ant to define a template based on ownership or how many instances are currently running, you can check the 'Unmatched procs' table on a particular host screen or the 'Processes not matched by this template' table on a template editing screen to get this information.
NO TE: If you w ant to define your application based on specific ownership, path, or command line arguments, you can check the 'Unmatched procs' table on a particular host screen or the 'Processes not matched by this template' table on a template editing screen to get this information.
3. Y ou can add a new type after "User" within the original And statement by clicking the Add Rule button at (below), or you can add additional statements or types after the original And statement by clicking the Add Rule button at . 4. Continue in this w ay until you hav e added all the types that you w ant in the rule.
The following figure shows an aggregation of multiple processes by specified executable path into one application. The following figure shows an aggregation of multiple processes specified using regular expressions . Ho w to Remo ve T y pes fr om the A ggr egation R ule Y ou might want to remov e types from a rule to correct it or refine it.
This example shows which Del Rule button to click to remove the Group type within an And statement and to remove the entire And statement. Chec k Unmatc hed Pr ocess es to F ind A pplicati on Candi da.
For more details about this part of an application template, see “Summary Fields and Their Descriptions” (page 34) . F illing in the T emplate A t tr ibute F ields In the following image, you can see the columns indirectly relevant to the Attributes fields in an application template – pid , ppid , user , sid , and ct .
On HP -UX: On HP-UX, HP Application Discovery program binaries are installed in /opt/amgr . HP Application Discovery data are located in / var/opt/amgr . T o back up HP Application Discovery , copy the entire contents of these two directories to storage media.

Check that the Application Discovery agent certificate has been installed on the managed node. T ype the following on the command line of the managed node: # ls /var/opt/amgr/ssl/agent_cert.
Hav e you r ecently restor ed or remov ed and reinstalled the CMS? : A restore or remov al of the central management server also remov es the certificate recognition previously established between Application Discov ery server on the CMS and Application Discovery agents on managed nodes.
T able 4 - 1 An Ex ample Comparison o f Matc h Behavior in AD and gWLM for Same Executable P ath and Arguments gWLM AD Example Inputs Process ar g[0] Executable match match /usr/sbin/biod /usr/sbin/biod match no match biod match no match ./biod not allowed match /usr/sbin/biod biod not allowed match biod not allowed match .
Once this action is taken, check that Application Discov ery is receiving messages from the host. (See #8 in this section.) 5. Check that SSH is configured correctly on the managed node . In this case, you may need to repair the HP Systems Insight Manager agent on the managed system.
See “Configuring the WBEM Provider P assword” (page 65) to learn how to configure the WBEM provider to complete this authorization. Alternatively , you can configure the managed system's WBEM authorization to trust the CMS to perform a remote "root" WBEM user logon.
When the v alues are not the same and the w arm-up ratio is less than 100%, this may indicate that an inventory is still being taken for that host. Expect the warm-up period for completing the package inventory to take about 20 minutes. 3. It is possible that certificate exchange has not been completed.
If you do not see this Jav a process, type /opt/amgr/bin/cms_start . Y ou must be logged in as user 'root' on the CMS to initiate this command. 2. Check that the host is known to Application Discovery . a. Click the following tabs in Application Discovery: Admin/Config , then Disco ver y .
4. Check to see if the workload is parked. A parked workload does not generate process maps anywhere. Process maps that existed prior to parking the workload are deleted. See the discussion of “General W orkload Properties ” in V irtualization Manager Help and the glossary for information about parked workloads.
NO TE: Be aware that one possible cause for incorrect configuration is the case where installation and startup deviate from the documented process. In this situation, you might see the following error message: Application Discovery UI encountered an error: The UI and server are out of sync.
