Custom alerts (Custom Alters), according to user-defined requirements do remind some fields set range, you can set up e-mail notification when the index exceeds the range set when the mailbox will automatically send messages to notify, inform the relevant personnel, can significantly reduce human workload.
Set in the position: selecting the "Custom" in the GA → "Custom alert" → "Manage Custom", shown in Figure 2-1:
Figure 2-1 Create a custom alert
After clicking the panel shown in Figure 2-2 is provided:
Figure 2-2 custom alert settings panel
Setting panel of each field listed in Table 2-1:
Table 2-1 custom alert parameter analysis
Custom alerts can follow the day, week and month setting, the basic approach is to use the selected indicators, such as session, the number of users, page views ...... method set limits generally speaking there are six kinds, the panel is inside. " Alert condition "was.
After the setup is complete, you can receive messages in different periods, to know whether there is an exception which indicators in to see specific targets, but do not look for more indicators every day.
Here I want to introduce another way, the principle has been removed with the smart set to do events: the calculation of the 90% confidence interval using the past month as the threshold data, specific set of threshold can be adjusted based on business needs for early warning needs to be done daily, usually two weeks need to do to update the threshold calculation. This is the approach on a statistical, more reasonable, but the delay GA original intelligent event is too long, impractical, so I removed, I generally recommend using this method to do the custom alert .
Below is an example to see how to calculate the threshold value, there is a lower limit: for example, I last week PV is: 250,320,450,420,230,321,451, can be calculated by Excel a mean of 349, referred to as a, a standard deviation of 92, referred is b, then the corresponding 90% confidence interval of the parameter n is 1.6465, the threshold range is [a-1.645 * b, a + 1.645 * b], then the custom alerts upper and lower limits of these two values is set up inside the lower different tables are upper and lower confidence interval of time corresponding to:
The greater the confidence, the greater the upper and lower section is more likely to fall within this range.
Application scenarios: core indicators and exception monitoring core products.
不足之处：GA的的数据延迟导致智能事件也会出现不同程度的延时，一般是两天左右；第二个是有时候原因没有列出来， 最重要的。
