Hello! My name is Koide from the System Development Department.
Today I would like to write about "website monitoring tools  "

It is extremely important to check whether any unintended problems with your website otherwise damaged by an external attack

For example, when a user visits a website, the site is slow to display or cannot be displayed

This may directly lead to a decline in usability and service image

 

A website monitoring tool allows you to centrally manage problems that occur during website operation .

However,

• "I don't know what kind of monitoring is necessary..."
• "I don't know what kind of website monitoring service I should introduce..."

Isn't there some people who are worried about this?

Therefore, in this article, server operation and maintenance for over 350 companies , and based on my knowledge as a member of a company with a high degree of infrastructure expertise,

• Items that can be monitored with website monitoring tools
• Recommended website monitoring tools

Introducing. Please watch till the end!

1. 4 monitoring items you must keep in mind when monitoring your website

You may be wondering to what extent you should monitor your website, but basically, if you monitor the following four items, you can ensure that your website is operating at a high quality. I can continue.

1. Communication check : Response speed time from when a user makes a request to receiving a response. Also called life and death monitoring.
2. Status code : A status code is a code that determines whether an HTTP request has been completed successfully. It is classified into 5 categories in total.
3. Checking the domain expiration date : Check the expiration date from the domain information registered in whois.
4. Checking the SSL expiration date : Check the expiration date of the SSL certificate.

I will explain each item below.

✔1-1. Check the communication status of the site “Communication check”

Communication check (aliveness monitoring) refers to the time from when a client sends a request (to view a website) until a response is returned (the website is displayed)

The longer you wait, the more likely your users will be frustrated and lose trust.

After all, everything is done quickly , but it is justice.

You can check the status of your site! status code

The status codes returned during HTTP communication can be broadly divided into 100s to 500s.

Below are the meanings and contents of the status codes by category.

 

It is also a status code that you often see on websites. It is sufficient to remember the following regarding status codes.

 

 

Do you tend to forget? Domain expiration date

Domains expire once a year, which is an infrequent task, so it's easy to forget to renew them.

The following article explains the problems that can occur when you forget your domain or SSL certificate.

[Easy] How to manage domain and SSL certificate expiry dates for free [Website operation]

With website monitoring tools, you can obtain the domain expiration date from the whois information and check it at any time.

Whois information is information that allows you to check information about IP addresses, domain name registrants, etc.

The image above is the whois information from our website.

You can see that the domain expiration date is displayed from the red line.

Essential for safe use of the site! SSL expiration date

Just like with domains, it's easy to forget to manage your SSL expiration date and end up panicking when it's about to expire.

If the SSL certificate expires, https communication will not be possible and the website will not display properly, so it is necessary to renew it as soon as possible.

Note that you can check the SSL expiration date by following the steps below even if you do not have a website monitoring tool.
(It's a pain to check each time, but...)

■Steps to check the SSL expiration date

• Step 1: Access the https URL in your browser and click the lock mark in the address bar.

• Step ② Click on the certificate

• Step ③ Click on the tab details

• Step 4: Check the fields for the start and end of the expiration date.

 

3. Introducing 4 recommended website monitoring tools

In the previous chapter, we explained the basic monitoring items that can be monitored with website monitoring tools and the details of each item.

Below we will introduce some website monitoring tools that are easy to install and have free plans.
Many website monitoring tools are available with free plans. The maximum number of URLs that can be monitored in the free plan and the functions that can be used differ
depending on the tool, so please check which tool is best for your purpose. It might be a good idea to try it out first and continue using the one that feels good.

If you are introducing a website monitoring (URL monitoring) tool, you should also check the monitoring interval.

Website monitoring (URL monitoring) tools have different monitoring intervals for each service. The monitoring interval is the frequency at which the system checks the status of your website.

The shorter the monitoring interval, the safer it will be, but depending on the application, such a short monitoring interval may not be necessary, so before introducing it, make a comprehensive comparison of other functions, the number of URLs that can be registered, etc. Deploy monitoring tools.

Furthermore, if the monitoring interval is 5 minutes, it can be said that the monitoring frequency is sufficient for peace of mind.

Especially in the case of free plans, there are many cases where the monitoring interval is longer, so it is a good idea to check in advance.

For your reference, here we will list the monitoring intervals of three typical website monitoring (URL monitoring) tools based on information published on the official website as of 2021.

summary

The most important thing you can do to avoid missing out on business opportunities with your website is to operate your website from the user's perspective

The most essential thing in this case is to maintain the communication status normally, and it is important to check the following four points.

• Communication check (response speed)
• status code
• Check domain expiration date
• Checking the SSL expiration date

It is difficult to monitor 24 hours a day, 365 days a year, so it is better to rely on external sites for monitoring.

The sites introduced this time are as follows.
