Since the contact information is free form, after the contact information has been obtained it will be necessary to parse it to extract the valid email address(es). The The module to do this should extract the userid before the @ symbol and the host name that follows the @ symbol. These should be validated to ensure the ID and name are correct. I believe the following regular expression can be used to check the hostname:
| Code Block |
|---|
$hostname=~/(([a-z0-9]+|([a-z0-9]+[-]+[a-z0-9]+))[.])+/
|
Or look at http://regexlib.com/DisplayPatterns.aspx you may be able to find a more complete solution
The modification would be needed in checkdata_gif.pl. It may be simpler in many cases to clean up the formatting of the email addresses in NODEDETAILS.
Second step
Once this is done,the next step would be to automate testing so that if we have not been able to see if:gather data from the site for the last 7 days (checkdata_gif.pl provides the number of adjacent days we have been unable to gather data from the site) or more then see if.
- the monitor is pingable from the host running the script,
- whether the monitor can ping your host (traceroute.pl?function=ping), assuming it has a remote traceroute server
- what a traceroute shows
- the ping_data.pl form appears, also note version of ping_data.pl
...
Eventually if automated the script may run once a week. In such a case checkdata.pl will need enhancing to also add the number of consecutive days we have been unable to gather data from the monitor on the 10th, 20th, 28th of the month. These dates are chosen to ensure there are already sufficient days in the month to be able to see enough days with no data.
Requirements
To make the pings one can look at the existing checkdata.pl since it provides the URL to make the calls to ping and can be extended to do a traceroute. However it is probably better to make the pings from the host running the script since it reduces the number of points of failure.
