L4 Proxy

Overview

EdgeOne provides data analysis and display of user access to L4 (transport layer) proxy instances by analyzing L4 access logs, including traffic, connection count, connection duration, and other data, helping you better monitor the operation of L4 proxy instances.

Supported capabilities

The L4 proxy analysis page supports the statistical display of traffic, connection count, connection duration, and other data for L4 proxy instances, and supports adding filtering conditions.




1. Data filtering and filtering

Supports selecting the time range for data query, for details, please refer to How to modify the query time range.
Supports filtering by site, service name, forwarding rules, country/region, and other dimensions, for details, please refer to How to use filtering conditions.

2. Core indicators

Outbound traffic: Traffic transmitted from EdgeOne nodes to clients.
Inbound traffic: Traffic received by EdgeOne nodes from client requests.
Connections: The number of connections that exist within the selected time range.
Connection time (95th percentile): For connections that exist within the selected time range, the 95th percentile of connection duration is calculated, i.e., this value is greater than 95% of other connection durations.

3. Time trend chart - Traffic

Displays the time-sharing trend curve of outbound and inbound traffic.

4. Time trend chart - Connection count

Displays the time-sharing trend curve of connection count.

5. Country/Region distribution

Displays the distribution of connection count in countries/regions.
Note:
1. The data here is based on the country/region of the client, and may differ from billing data. The regional distribution of billing data is based on the actual region where the EdgeOne node serving the client is located.
2. Due to the delay and algorithm, the country/region distribution is for reference only, and it is suggested to refer to the actual log analytics results.

6. Connection duration distribution

Displays the histogram distribution of connection duration.

Analysis examples

Scenario 1: Monitor the traffic and connection count indicators of L4 proxy instances in a certain country

Under certain filtering conditions, the time trend chart on the L4 proxy analysis page can be used to monitor the operation of L4 proxy instances.

Scenario example

After you create a new L4 proxy instance, if you want to monitor the traffic and connection count indicators of the L4 proxy instance named example in Singapore, you can perform the following operations in the Data Analysis > L4 Proxy page.

Directions

1. Log in to the EdgeOne console, click on the site list in the left menu bar, click on the site you are interested in within the site list, and enter the site details page.
2. In the site details page, click on Data Analysis > L4 Proxy to enter the L4 Proxy page.
3. In the L4 Proxy page, click Add Filter, add filtering conditions Service Name=example Country/Region=Singapore, and click Confirm.
4. View the time trend chart of traffic and connection count, observe whether there is a sharp increase or decrease, and determine whether the business you are concerned about is running normally.

Scenario 2: View the overall operation trend of L4 proxy instances for all sites

Scenario example

After you have added multiple L4 proxy instances to multiple sites and they have been running stably on EdgeOne for a period of time, you may want to regularly inspect the traffic trend of L4 proxy services usage for all sites in the console. You can follow the steps below.

Directions

1. Log in to the EdgeOne console, click on Data Analysis > L4 Proxy in the left menu bar, and enter the aggregated data analysis page for multiple sites.
2. View the time trend chart, observe whether the traffic and connection count have a sharp increase or decrease, and determine whether the overall business is running normally.
3. In the connection count card, click Compare Data to compare the traffic curve for the same time period in the last two days, and observe whether the business has a sudden increase or decrease in day-to-day comparison.
