File Channel

Technical Prerequisites

 The technical prerequisites depend on which of the monitoring templates you want to use.

Template Technical Prerequisites
File (Diagnostic Agent) A current version of the Diagnostics agent must be installed on the host where the file is located. Please refer to SAP note 1858920 to find out how to install the latest version of the Diagnostics agent and how to access PAM to check if the Diagnostics agent is available for the operating system the host is running on. 
File (ABAP)

The following technical prerequisites need to be fulfilled to use this monitoring template:

  • Managed system has SAP Basis release ≥ 7.00
  • ST-A/PI add-on with at least version 01R needs to be installed on the managed system.

To use this monitoring template the respective managed system (i.e. the system in which the data collector is executed) requires file level access to the folder containing the file to be monitored. To test whether the collector can access this folder, you can check whether folder and file are visible in transaction AL11 of the managed systems. In addition, the user executing the data collection (user maintained in the TMW RFC destination to the managed system) needs to have the authorization to access files (authorization object S_CTS_ADMI, field CTS_ADMFCT = EPS1). See SAP note 1267908 for further details.
File (Remote)

The following technical prerequisites need to be fulfilled to use this monitoring template: 

  • SAP Solution Manager is running on SAP Solution Manager 7.1 SP 14 or higher
  • The remote server where the file is located must run an (S)FTP server

Available Monitoring Content

Monitoring Template: File (Diagnostic Agent)

The metrics are provided via a data collector on the Diagnostics agent. This agent can be deployed on numerous types of hosts and operating systems. It doesn't require any SAP system to be running on this host. So this agent can also by used to monitor non-SAP hosts.

If you want to monitor the content of XML files please refer to the File (ABAP) monitoring template.

Metric Name Description MAI Category Since SP

Number of Files available

Number of files which matches the configured pattern.

Availability

 7.1 SP10

File Content Scanner (Average)

This metric aggregates all values in a file which are found after a specific search pattern + offset.

Exception

 7.1 SP12

File Content Scanner (Sum)

This metric sums up all values in a file which are found after a specific search pattern + offset.

Exception

 7.1 SP12 

Age of File

Age (in min) since last modification. If more than one file fits the pattern for the file name the time of the latest modification is returned.

Performance

 7.1 SP10
Last Folder Update

This metric measures the time (in minutes) since last modification of the configured folder. Usually, the Last Modified time stamp of a folder is updated in case files within the specified folder are created or deleted.

 Performance 7.2 SP05

Number of Entries within a File

Number of entries (lines) within a file.

Performance

 7.1 SP12

Number of Pattern Matches within a File

Number of entries within a file which match a specific search pattern.

Size of File

Total size in Byte of the configured file(s). If more than one file fits the pattern the total size of all files is returned.

Performance

 7.1 SP10

Monitoring Template: File (ABAP)

The metrics are provided via the ST-A/PI-based file monitoring functionality. Be aware that the ST-A/PI-based file monitoring is only capable to monitor files located in an ABAP-based SAP system.

Metric Name Description MAI Category Since SP

Creation time of file

This metric monitors whether the specified file exists at the specified location at the time of the data collection or at a specified point in time. Since the time stamp checked is the stamp for “change”, the monitoring effectively determines if a file was created or updated until a certain point in time.

Exceptions

 7.1 SP12

Number of Pattern Matches within a File (XML)

Counts how often a pattern occurs between certain tags in an XML file.

Performance

 7.1 SP12

File Content Scanner (XML)

Calculates aggregates (e.g. MIN, MAX, AVG,… ) of values occurring between specified tags in an XML file.

Exceptions

 7.1 SP12

Monitoring Template: File (Remote)

This monitor uses a direct native access to the remote SFTP server. It is not necessary to have a diagnostics agent installed on the SFTP server. One of the Solution Manager Diagnostics agents will be used during the setup. The diagnostics agent will connect from the Solman network segment, only the access to the remote SFTP server is required (host, port). 

Metric Name Description MAI Category Since SP
Size of File This metric measures the total size in Byte of the configured file(s). Performance 7.1 SP14
File exists Availability of configured files Availability 7.1 SP14 
Age of File This metric measures the time (in min) since last modification of the configured file(s). Performance 7.1 SP14

    • Group variants: Group metric variants if more than one file matches the selection criteria.

Select Metrics:

  1. On the Metrics tab, select the metrics you want to monitor. Note that the selected metrics are collected for each file interface entered above.

You can maintain attributes as described in the Interface and Connection Monitoring Setup on the Attributes tab.

Thresholds and the collection schedule are maintained in the next step of the guided procedure. Once you have maintained all your channels, click Next in the main guided procedure to move to the Activation step.

Maintain Thresholds and Schedule:

  1. Select the Alert for the channel (the alert is the line with the red flash icon next to it)
    • On alert level you can maintain notification and incident message creation.
  2. Select the Metrics

    • You can change the collection interval. You can use advanced scheduling with this monitor. This allows you to monitor only at very specific times.
    • On the Overview tab, you have to select which Collector Context you want to use for the data collection. The collector context defines the diagnostics agent that will perform the data collection. By default, the diagnostics agent on SAP Solution Manager will perform the data collection. You can choose from the following options:
      • Source: the diagnostics agent on the source system (must be type Host or Technical System)
      • Target: the diagnostics agent on the target system (must be type Host or Technical System)
      • Solution Manager: the diagnostics agent on SAP Solution Manager
      • Host: any host in the managed system landscape
      • System: any system in the managed system landscape
  3. Click Apply and Activate → <Choose one option> to activate the monitoring

 

Note: Advanced Configuration for Collector Context

If you select another collector context, e.g. if you have a specific agent installed on a host or system you want to use or if you need to use another agent because network restrictions on the SAP Solution Manager agents.

However to enable another host or system to collect the information you have to move the (S)FTP configuration. By default, when you maintain an (S)FTP standalone server in transaction S2S_SETUP the login and connection information to the (S)FTP server are stored in the scope of the Solution Manager diagnostic agent(s).

The easiest way to enable the complete free selection of agents and systems is to move this configuration to the Global scope where it is accessible for all agents. 

  1. Open the Diagnostics Agent Administration and navigate to the Application Configuration tab.
  2. Select the agent application com.sap.smd.agent.application.global.configuration.
  3. Select the agent on SAP Solution Manager for the scope.
  4. You will find the following entries in this agents configuration:
    • FTP_SFTP_<X>/host = hostname of the remote host (FQDN)
    • FTP_SFTP_<X>/password = <password>
    • FTP_SFTP_<X>/port = (S)FTP port of the remote host
    • FTP_SFTP_<X>/protocol = FTP or SFTP
    • FTP_SFTP_<X>/timezone = time zone of the remote host
    • FTP_SFTP_<X>/user = <user>
  5. Write down this information.
  6. Switch back to <Global> scope
  7. Switch to Edit mode
  8. Add the properties above to the global scope
    • Make sure to select Secure Property when you enter the password.
  9. Save to push the new properties to all agents.

If you only want to save the properties on a specific agent you could do this as well. It is done the exact same way, but instead of the Global scope you select the scope of the agent you want to change.

After saving you can select whatever agent has the configuration in the scope selection of the interface channel activation. Please note, that only hosts and systems that have SMD agents installed will work.
