Label:I have been using seconds_behind_master to measure the master-slave delay, today I see the document, how unreliable! The following is a description of the official documentation: In essence, this field measures the time difference in seconds between the slave SQL thread and the slave I/O thread. In other words, this variable describes the time difference between I/O thread and SQL thread from the library. The following uses Pt-heartbeat to monit

the unit; 3. Recalculate the EM values of the enlarged fonts. Avoid duplicate declarations of font size. That is to avoid the 1.2 * 1.2 = 1.44 phenomenon. For example, if you declare a font size of 1.2em in #content, then you can only 1em when declaring P's font size, not 1.2em, because this em is not the other em, and it becomes 1em=12px because it continues to #content the font height. But the exception of 12px Chinese characters is that the 12px (1.2em) size of Chinese characters obtained

For MySQL database master-slave replication delay monitoring, we can rely on Percona's powerful weapon pt-heartbeat to achieve. Pt-heartbeat updates a specific table on the main library by using timestamp, and then reads the updated timestamp from the library and then compares it with the local system time to get its delay. This article is mainly through the script regularly check the delay from the library
