Web Monitoring Methods

Using Right Web Monitor you can monitor various Internet resources for changes. Every kind of resource requires a special checking method to get relevant result. Usually Right Web Monitor automatically decides which method to use with certain resource, however you can adjust that manually if you want to use another one. Here goes the list with checking methods and short explanations how they work:

HTTP/HTTPS resources checking methods:
- Resource Size/Date/Time comparing - this method is suitable for static documents, binary files etc. This is the fastest checking method and it uses the lowest amount of Internet traffic because Right Web Monitor asks a web site to return only size and date/time of the last resource update without accessing to resource content. After receiving the response from the web site Right Web Monitor compares is with the results of previous check and presumes that resource has been modified if the results differ from each other. This check method isn't suitable for checking dinamically generated web pages (various asp and php scripts etc.) since usually website returns zero last modification date. It is recommended to use the next checking method to check such pages.
- Exact Content Analysis - this method is slower and consumes more traffic compared to previous one, since Right Web Monitor downloads entire webpage and compares it with previously saved page. The webpage is presumed changed if they differ from each other. This method isn't suitable for checking large binary files because the amount of Internet traffic it uses (the bigger the file - the bigger the amount of traffic if will use). Also this method isn't suitable for pages with dinamic elements (like clocks, visitor counters, dinamic links etc.) since every time Right Web Monitor will check such pages it will receive different results (new clock values, increased visitor counters, new links etc.). It is recommended to use the next checking method to monitor such kind of pages.
- Smart Content Analysis - this method is also more time/traffic consuming then "Resource Size/Date/Time" method, because when using it Right Web Monitor also downloads entire web document to compare it with the previously saved one, however comparison goes different way. The program uses various user-defined analysing rules to check the document for changes. You can learn more about these rules by reading Smart Content Analysis Check Method document.
- RSS feeds processing - this method is suitable for cheking RSS feeds. When using it Right Web Monitor just downloads RSS feed and check if there are something new in it.
FTP resources checking methods:
- Single file checking - Right Web Monitor asks FTP server for file size and last modification date/time and compares them with previously saved values. Resource is presumed changed if those differ from each other.
- Folder monitoring - Right Web Monitor asks FTP server for file listing for the folder and compares it with previously saved one. Resource is presumed changed if those differ from each other (i.e. some files have been added, changed or deleted).
- Folder monitoring with subfolders processing - Right Web Monitor asks FTP server for file listing for the folder, fetches the names of subfolders and asks file listings for them and so on until the lowest level subfolders. After receiving all the listings the program compares entire listing with previously saved one. Resource is presumed changed if those differ from each other (i.e. some files have been added, changed or deleted) considering extension filters (i.e. presume resource modified if any files changed, if files with certain extensions changed or if any but files with certain extensions changed). This feature is avaiable in Pro version only.
POP3 mail box checking - Right Web Monitor asks mail server for letter list and checks it. Resource is presumed modified if any new letters are detected.
ICMP site availability checking (ping) - Right Web Monitor sends ICMP packets to a host and checks received results. The program will notify you if percetage of losses is equal or above certain number (configurable), if the response time goes upper then certain value (configurable) or if "Up"/"Down" state changes (configurable). This feature is available in Pro version only.

So, as you can see, using Right Web Monitor you can check Internet resources exactly as you need. Now let's see how to configure Right Web Monitor to check different resource types. Here goes the list with links to pages which contain detailed descriptions of how to do that:
