 ## Installed Collectors and Sources in action
 
 This section is an overview of how Installed Collectors and their Sources operate.
 
 ### Installed Collector startup
 
-When you start up an Installed Collector for the first time it registers with Sumo and creates any Sources that you have defined in a UTF-8 encoded JSON source configuration file.
+When you start up an Installed Collector for the first time it registers with Sumo Logic and creates any Sources that you have defined in a UTF-8 encoded JSON source configuration file.
 
-When the collector tries to register with Sumo it first sends the request to the US1 deployment. If your organization is in another deployment Sumo will redirect the Collector to your deployment URL based on the authentication credential's deployment. You can define the deployment URL in the Collector's [user.properties](collector-installation-reference/user-properties.md) file with the `url` parameter.

 ### Sources scan source data
 
 Sources scan their target directory or data structure periodically. A Local File Source scans target directories every two seconds. For Windows Performance Monitor Sources and Script Sources, you configure the scan interval when you define the source.
 
 For support purposes, an Installed Collector automatically collects its version, uptime, OS version, OS architecture, Java version, and JVM instance ID. Installed Collectors running on AWS also collect instance type, instance ID, and instance region.

+### How an Installed Collector sends data to the Sumo Logic service
 
-An Installed Collector starts sending data to the Sumo service as soon as it is available from the Sources configured on the Collector. Before sending the data, a Collector compresses (by a factor of 10x) and encrypts the data. A Collector sends data to the Sumo service over HTTPS.

 #### Fingerprint
 
-To keep track of what it has already sent to the Sumo service, the Collector tracks a file by its fingerprint (the first 2048 bytes of the file) and by a read pointer that indicates the last line read by the Collector. This fingerprint is then compared to a list of known fingerprints from that Source. If the fingerprint does not match one in the known list we start reading that file's content from the beginning and send it to Sumo. If a matching fingerprint is found in the list we start reading from the last known byte mark of that file. The Collector updates this information approximately every second. A file's fingerprint is retained for some period of time after file deletion, otherwise it is removed.

 An issue that could arise is seeing duplicated log messages for a log file that is written to very slowly. When a file is slowly written and the first messages in the file are not larger than 2kb the fingerprint for the Source file can be overwritten with each log line, up to the point those first lines add up to 2kb.

 ### Throttling, caching, and flushing
 
-Ordinarily, a Collector sends data to the Sumo service as fast as its connection allows. Under some circumstances, the Sumo service may instruct a Collector to throttle itself or slow the rate at which it is sending data to the service. 
+Ordinarily, a Collector sends data to the Sumo Logic service as fast as its connection allows. Under some circumstances, the Sumo Logic service may instruct a Collector to throttle itself or slow the rate at which it is sending data to the service. 
 
-To determine whether throttling is required, Sumo measures the amount of data already committed to uploading against the number of previous requests and available resources (quota) in an account. In other words, Sumo Logic compares the current ingestion with the rate of ingest using a per minute rate that can be derived from the contracted daily GB/day rate.

 The Collector uses the log4j2 framework. You can tailor log rotation behavior for `collector.log` by editing the `log4j2.xml` file in the collector’s `/config` directory. For more information, see Log Rotation Settings.
