    Hi,

    have you look this plugin?

    Code:
    /usr/local/nagios/libexec/check_http --help
    
    check_http v1.4.15 (nagios-plugins 1.4.15)
    Copyright (c) 1999 Ethan Galstad
    Copyright (c) 1999-2008 Nagios Plugin Development Team
    
    
    This plugin tests the HTTP service on the specified host. It can test
    normal (http) and secure (https) servers, follow redirects, search for
    strings and regular expressions, check connection times, and report on
    certificate expiration times.
    
    
    Usage:
    check_http -H | -I [-u ] [-p ]
    [-w ] [-c ] [-t ] [-L] [-a auth]
    [-b proxy_auth] [-f ]
    [-e ] [-s string] [-l] [-r | -R ]
    [-P string] [-m :] [-4|-6] [-N] [-M ]
    [-A string] [-k string] [-S] [--sni] [-C ] [-T ]
    [-j method]
    NOTE: One or both of -H and -I must be specified
    
    Options:
    -h, --help
    Print detailed help screen
    -V, --version
    Print version information
    -H, --hostname=ADDRESS
    Host name argument for servers using host headers (virtual host)
    Append a port to include it in the header (eg: example.com:5000)
    -I, --IP-address=ADDRESS
    IP address or name (use numeric address if possible to bypass DNS lookup).
    -p, --port=INTEGER
    Port number (default: 80)
    -4, --use-ipv4
    Use IPv4 connection
    -6, --use-ipv6
    Use IPv6 connection
    -S, --ssl
    Connect via SSL. Port defaults to 443
    --sni
    Enable SSL/TLS hostname extension support (SNI)
    -C, --certificate=INTEGER
    Minimum number of days a certificate has to be valid. Port defaults to 443
    (when this option is used the URL is not checked.)
    
    -e, --expect=STRING
    Comma-delimited list of strings, at least one of them is expected in
    the first (status) line of the server response (default: HTTP/1.)
    If specified skips all other status line logic (ex: 3xx, 4xx, 5xx processing)
    -s, --string=STRING
    String to expect in the content
    -u, --url=PATH
    URL to GET or POST (default: /)
    -P, --post=STRING
    URL encoded http POST data
    -j, --method=STRING (for example: HEAD, OPTIONS, TRACE, PUT, DELETE)
    Set HTTP method.
    -N, --no-body
    Don't wait for document body: stop reading after headers.
    (Note that this still does an HTTP GET or POST, not a HEAD.)
    -M, --max-age=SECONDS
    Warn if document is more than SECONDS old. the number can also be of
    the form "10m" for minutes, "10h" for hours, or "10d" for days.
    -T, --content-type=STRING
    specify Content-Type header media type when POSTing
    
    -l, --linespan
    Allow regex to span newlines (must precede -r or -R)
    -r, --regex, --ereg=STRING
    Search page for regex STRING
    -R, --eregi=STRING
    Search page for case-insensitive regex STRING
    --invert-regex
    Return CRITICAL if found, OK if not
    
    -a, --authorization=AUTH_PAIR
    Username:password on sites with basic authentication
    -b, --proxy-authorization=AUTH_PAIR
    Username:password on proxy-servers with basic authentication
    -A, --useragent=STRING
    String to be sent in http header as "User Agent"
    -k, --header=STRING
    Any other tags to be sent in http header. Use multiple times for additional headers
    -L, --link
    Wrap output in HTML link (obsoleted by urlize)
    -f, --onredirect=
    How to handle redirected pages. sticky is like follow but stick to the
    specified IP address. stickyport also ensure post stays the same.
    -m, --pagesize=INTEGER<:INTEGER>
    Minimum page size required (bytes) : Maximum page size required (bytes)
    -w, --warning=DOUBLE
    Response time to result in warning status (seconds)
    -c, --critical=DOUBLE
    Response time to result in critical status (seconds)
    -t, --timeout=INTEGER
    Seconds before connection times out (default: 10)
    -v, --verbose
    Show details for command-line debugging (Nagios may truncate output)
    
    Notes:
    This plugin will attempt to open an HTTP connection with the host.
    Successful connects return STATE_OK, refusals and timeouts return STATE_CRITICAL
    other errors return STATE_UNKNOWN. Successful connects, but incorrect reponse
    messages from the host result in STATE_WARNING return values. If you are
    checking a virtual server that uses 'host headers' you must supply the FQDN
    (fully qualified domain name) as the [host_name] argument.
    
    This plugin can also check whether an SSL enabled web server is able to
    serve content (optionally within a specified time) or whether the X509
    certificate is still valid for the specified number of days.
    
    Examples:
    CHECK CONTENT: check_http -w 5 -c 10 --ssl -H www.verisign.com
    
    When the 'www.verisign.com' server returns its content within 5 seconds,
    a STATE_OK will be returned. When the server returns its content but exceeds
    the 5-second threshold, a STATE_WARNING will be returned. When an error occurs,
    a STATE_CRITICAL will be returned.
    
    CHECK CERTIFICATE: check_http -H www.verisign.com -C 14
    
    When the certificate of 'www.verisign.com' is valid for more than 14 days,
    a STATE_OK is returned. When the certificate is still valid, but for less than
    14 days, a STATE_WARNING is returned. A STATE_CRITICAL will be returned when
    the certificate is expired.

    Centreon just have 'check_http' in it default config template, it just check if http is available but as you can see, it have many other option.
    you could create a other command check in centreon, which for exemple seach in page for regex STRING or other...
