Monitoring a Website URL Using check_http<\/strong><\/h2>\n\n\n\nNagios includes the check_http<\/code><\/strong> plugin, which allows monitoring of a specific webpage instead of just checking whether Apache is running.<\/p>\n\n\n\nThis method is useful when:<\/p>\n\n\n\n
\n- A website is hacked or injected with malicious code<\/li>\n\n\n\n
- PHP or application errors occur<\/li>\n\n\n\n
- Pages return unexpected content<\/li>\n<\/ul>\n\n\n\n
You can configure Nagios to verify whether a specific keyword exists on a webpage. If the keyword is missing, Nagios reports the service as failed.<\/p>\n\n\n\n
Example Configuration<\/h3>\n\n\n\ndefine service{
use urlmonitoring-service
host_name server.supportpro.com
service_description url_check
check_command check_http!-H supportpro.com -t 30 -R \"Cpanel and WHM\" -f follow
}<\/code><\/pre>\n\n\n\nThis configuration checks whether the phrase \u201cCpanel and WHM\u201d<\/strong> exists on the webpage.
If the page fails to load or the keyword is missing, Nagios triggers an alert.<\/p>\n\n\n\nMonitoring HTTPS (SSL\/TLS) URLs<\/strong><\/h2>\n\n\n\nFor websites using SSL certificates, include the --ssl<\/code> option:<\/p>\n\n\n\ndefine service{
use urlmonitoring-service
host_name server.supportpro.com
service_description url_check
check_command check_http!-H supportpro.com -t 30 -R \"Cpanel and WHM\" -f follow --ssl
}<\/code><\/pre>\n\n\n\nMonitoring Password-Protected Pages<\/strong><\/h2>\n\n\n\nIf a webpage is protected using HTTP authentication<\/strong>, credentials must be provided.<\/p>\n\n\n\ndefine service{
use urlmonitoring-service
host_name server.supportpro.com
service_description url_check_protected
check_command check_http!-H supportpro.com -a user:password -t 30 -R \"Cpanel and WHM\" -f follow --ssl
}<\/code><\/pre>\n\n\n\nReplace user:password<\/code> with valid authentication credentials.<\/p>\n\n\n\nCreating a Service Template<\/strong><\/h2>\n\n\n\nEnsure the monitoring template exists in your Nagios configuration:<\/p>\n\n\n\n
define service{
name urlmonitoring-service
max_check_attempts 5
check_interval 15
retry_interval 2
check_period 24x7
notification_interval 30
notification_period 24x7
register 0
}<\/code><\/pre>\n\n\n\nThis template defines monitoring intervals, retry attempts, and notification settings.<\/p>\n\n\n\n
Conclusion<\/strong><\/h2>\n\n\n\nNagios URL monitoring provides deeper insight into website health by validating actual page content rather than only service availability. Using the check_http<\/code> plugin helps quickly detect downtime, application errors, security issues, and performance problems.<\/p>\n\n\n\nIf you require help, contact SupportPRO Server Admin<\/a><\/p>\n\n\n\n<\/a><\/span><\/span><\/p>\n\n\n\n\nFacing issues? <\/p>\n\n\n\n
