Network Service Monitors

Before You Begin

Before configuring the DNS monitor, determine the IP address for the host that you want to monitor. For internal hosts, you can use the ipconfig command from the command line.

The ipconfig command returns information similar to the following:

Connection-specific DNS Suffix . . : uptimesoftware.com
IP Address . . . . . . . . . . . . : 10.1.1.42
Subnet Mask . . . . . . . . . . . .: 255.255.255.0
Default Gateway . . . . . . . . . .: 10.1.1.1

For external hosts, you can use the nslookup command from the command line as follows:

nslookup <host name>

The nslookup command returns information about the host, similar to the following:

Server: filter.uptimesoftware.com
Address: 10.1.1.100

Name: uptimesoftware.com
Addresses: 217.160.226.70, 10.1.1.95, 
192.168.23.1, 192.168.190.1

Configuring HTTP (Web Services) Monitors

To configure HTTP (Web Services) monitors, do the following:

1. In the HTTP (Web Services) monitor template, complete the monitor information fields.
2. To learn about monitor information fields, see Monitor Identification.
3. Complete the following fields:
   
   • URI
     The URI of the Web page that you want to monitor. For example, 
     /login.php .
   • Text to Look For (Optional)
     Enter the text that you want the monitor to search for in the response from the server.
     This monitor parses the text from the server and, using the threshold values you enter, determines if the entire Web page returned by the server is within acceptable parameters.
     For example, if a Web page is returned then the monitor parses the entire page for the text that you input to match against. If you want to ensure that a particular page is returned, you could enter <TITLE>Expected Page</TITLE> , where Expected Page is the title of the Web page. The monitor generates an alert if this page is not matched.
   • Authentication
     The user ID and password, in the form userid:password . For example:
     jlamport:bluefrog5
   • Virtual Host
     The unique domain name that resolves to the IP address of the domain that you want to monitor. A virtual host has its own domain name, but has the same IP address as other domain names hosted by the Web server.
   • Server Response
     Enter a string to match against the response from the server. For example, HTTP/1.1 200 OK or HTTP 404 - File not found . Then, set the Warning and Critical comparison methods. For more information, see Configuring Warning and Critical Thresholds
   • Follow Redirect Actions
     Select an action that enables you to specify whether or not you want to be redirected to another Web address:
     
     • OK
       Return an OK status for any re-direction.
     • Follow
       Follow any re-direction.
     • Warning
       Return a Warning status for any re-direction.
     • Critical
       Return a Critical status for any re-direction.
   • POST String
     The URL-encoded POST string to be sent to the server. This string simulates what a Web browser sends to a Web server CGI script or binary. You can use the POST string to, for example, simulate logging into a Web application.
     For example, if you define the POST string as userid=bob&sku=123456 , the page to request would be /cgi-bin/sku_lookup . The text “ SKU count is ” is the expected response. If the SKU lookup is not successful or if the response from the application server is not fast enough, then up.time generates an alert.
   • Set-Cookie String
     The parameters that define the cookie. The cookie string uses the following format:
     domain:name:value:path
     If configuring multiple cookies for the monitor, separate each cookie string with a semicolon:
     
     •  domain is the subdomain the cookie is available to.
     •  name is a name with which you can later reference the cookie.
     •  value is a regular string to be stored as a cookie. The string should be encoded using URL-style %xx encoding, which converts all reserved and unsafe characters - such as tildes (~) and spaces - to their ASCII equivalents.
       For example, using %xx encoding, the URL http://www.mydomain.com/~jdoe/index.html becomes http://www.mydomain.com/%7ejdoe/index.htmlpath is the location on the server in which the cookie has been made available. For example, if the path is “ / ” the cookie is available to the entire domain, as opposed to a specific subdirectory name.
       d1:n1:v1:p1;d2:n2:v2:p2
       The name and value pair is the only required attribute of the Set-Cookie String field.
   • HTTP Header Settings
     The HTTP header settings for the response.
     The HTTP header settings define the syntax and semantics of all standard HTTP/1.1 header fields. For entity header fields, both sender and recipient refer to either the client or the server, depending on who sends and who receives the entity.
   • Response Time
     Enter the Warning and Critical Response Time thresholds. For more information, see Configuring Warning and Critical Thresholds
4. Click the Save for Graphing checkbox to save the data for a metric to the DataStore, which can be used to generate a report or graph.

SNMP OID Data Types and Formats

The SNMP service monitor will work with the OID data types listed below. When configuring an SNMP Poller, you will be able to specify whether the service monitor will process different data value formats (e.g., an SnmpInt object’s returned value can be processed by the service monitor as a string or an integer). The following table also outlines correct data type and value format combinations.

Adding MIBs to up.time

up.time ships with a large set of MIBs that are available when configuring an SNMP Poller. The resulting OIDs are viewed in the MIB Browser, which is displayed when creating or editing an SNMP Poller service monitor.

If desired, you can add new MIBs to augment or replace OIDs in the default list. These MIBs should be copied to the <uptime>/mib directory. If you are considering adding your own MIBs to this directory, consider the following:

• when adding MIBs, ensure you are observing their dependencies
• after adding MIBs, restart the up.time Data Collector service (see Stopping and Restarting up.time Services); upon restarting, up.time will move the newly added MIBs to the DataStore for use by the MIB Browser
• added MIBs are processed alphabetically, so an identically named OID from a later MIB will take precedence; note that the default MIBs included with up.time will always be parsed before other MIBs

Note that there is a core set of MIBs that up.time ’s SNMP functionality requires. The nodes belonging to these MIBs will always take precedence over any others added to up.time :

• SNMPv2-SMI
• SNMPv2-TC
• SNMPv2-CONF
• SNMPv2-MIB
• RFC1213-MIB
• IF-MIB
• HOST-RESOURCES-MIB

Understanding Port Status Checks

The port status check triggers an alert when a port’s ifOperStatus state changes from an “ up ” to a “ down ” state from one check to the next. Note that the following port states are ignored:

• dormant
• lowerLayerDown
• notPresent
• unknown
• testing

The status check makes use of data retrieved by the assigned network device’s Platform Performance Gatherer service; it does not rely on an external service check, such as a ping monitor. As such, when configuring the port monitor, ensure its Performance Time Interval and Check Interval settings are complementary (e.g., the status check should occur less frequently than how often performance data is gathered).

If a status-checking port monitor is running for the first time, since there is no last known status for comparison, the monitor will treat the port’s status as “up”, and re-check at configured intervals for the next 60 minutes. After this period, the port monitor’s status will be reset to OK . This behavior exists to prevent false positives where an administrator has removed network cables during maintenance, but has not set the network device’s ifAdminStatus to “ down ” or “ testing ”.

This first-run behavior is also applicable to other scenarios:

• the network device to which the port monitor is attached has its state changed to MAINT , then back to OK
• the Core service is restarted, regardless of the network device’s status

Network Device Port Performance Metrics

The following metrics can be used to configure alert thresholds for a port monitor:
