What is splunk?
Cloud-oriented log search engine is a powerful log management software. You can add local or remote logs in multiple ways and generate graphical reports. The most powerful feature is its search function-so it is called "Google for it ".
Features:
1. Supports multi-platform Installation
2. Any data is obtained by any source.
3. Get the forwarded data from the remote system
4. Associate Complex events to generate a Visual View

1. indexer indexes local or remote log data.
Working mechanism:
You can index log data of any format with a timeline. This index is used to disrupt data and put it into events based on the timestamp. Each events contains the timestamp, host, source, and source type attributes. A log row is an event. xml logs may be divided into multiple events. When a user searches, these events are searche

The benefit of increasing the switching frequency is obvious, but there are some shortcomings, designers should understand the pros and cons, in order to choose the most suitable switching frequency to be applied. This practical article will explain these considerations one by one.
DC power converters with high switching frequencies are becoming popular because they can save board space with

Brief analysis: During the opening of the switching tube s, the current is charged to the capacitance C through the switch tube and inductance.
When the switching tube s is off, the filter capacitance C is charged to r, because the inductor current cannot be mutated, through the RC circuit, D discharge
Brief calculation:
When the switch tube is on, there is
