Resource Check Profiles

Site24x7 Server monitoring includes monitoring of internal resources like files, event logs, syslogs, and directories on a server by creating them as a resource check. To start monitoring these resources, first create a Resource Check Profile by grouping different resource checks together. A single Resource Check Profile can be associated with multiple server monitors.

    • http://localhost
    • http://localhost/sample
    • http://$$HOSTNAME$$:8080
  4. Click Save to add the new URL Check.
Note

  • The URL value must begin with either http:// or https://. This can be followed by the host name and optionally, the port [https://host:8080]. The host name can be given as localhost or the machine name can be specified.
  • Both root and non-root URLs are supported.
  • The hostname can be denoted as $$HOSTNAME$$ and the IP address can be denoted as $$IP$$ to apply the same profile to multiple server monitors. Accordingly, the server hostname and IP address will be replaced.
  • Duplicate URLs [https://$$IP$$:8444] cannot be added to the same Resource Check Profile.

Alerting mechanism:

Ensure the option Alert when a resource check fails is set to Yes in the associated server's threshold profile to trigger a Critical, Down, or Trouble alert for the configured check. When the configured URL goes down, the resource check will be marked as DOWN and the status of the associated server monitor(s) will be changed to Critical, Down, or Trouble till the URL is active again.

Port Check

Get alerted whenever a port is down in your server. Create a Port Check to monitor the ports in a server. To configure this check, follow the steps below:

Regular Expressions

A regular expression (RegEx) is a special string of text used to describe a search pattern. In addition to plain text, regular expressions have special characters with special functions for matching string patterns (names).

Regular expressions are an extension to wildcards. [*] is a popular wildcard used to denote any text. For instance, you can search for all .txt files in a file manager with the wildcard notation *.txt . A RegEx for a similar search would look something like .*\.txt 
where,

  • the first '.' matches any character
  • '*' represents that the preceding symbol or group can occur zero or more times
  • '\.' denotes the character '.'
  • 'txt' denotes the string txt

Some common RegEx notations are*:

^ Start of line
$ End of line
. Matches any character
\d Matched digits 0-9
\s Matches whitespace
\S Matches non whitespace
[A-Z] Matches any capital alphabet. [] is used to represent a set.
[a-z] Matches any small alphabet
* Quantifier - Matches the preceeding group 0 to any number of times
+ Quantifier - Matches the preceeding group 1 to any number of times
(.*) Capturing group that matches any character 0 to any number of times
| Or
^([A-Z]*[a-z]*)$ Capturing group to match a string with all capital letters or all small letters
^(www\.site24x7\.com)$ Matches www.site24x7.com. \ is an escape symbol. Anything following it is matched, even if it is a special symbol.

*Includes only basic samples of regular expressions. It is recommended to test RegEx before using it to configure a resource check.

View History of the configured resource checks

You can view the changes that happened over different time periods for each of your resource checks configured. Follow the steps below:

  1. Log in to your Site24x7 account and go to Server > Server Monitor > Servers > click on the associated server monitor > Checks.
  2. Click View History beside the check for which you would like to view the list of changes.
    view history location
  3. Choose the time period from the drop-down and view changes that have been made for that period of time.
    resource check history

Security

  • Read-Only permission is required to monitor the files, directories, and logs.
  • Only the meta data is accessed to monitor these resources, and not the entire content.* 
  • For event logs and syslogs, data is not stored anywhere, but only taken from the client servers and presented in the web client.

*An exception is Content Check, where the entire content in the file/directory is accessed, with a Read-Only permission.
