yproxy

yproxy - a service for efficient transfer data external storages.

debugging

1. set debug_port and debug_minutes in configuration file
2. send SIGHUP to yproxy
3. target golang tools to /debug/pprof to profile application

metrics

yproxy gather and report various internal metrics in a prometheus format. To get metrics query yproxy use http, default metrics port is 2112, curl example:

curl localhost:2112/metrics

The output consists of 2 categories of metrics:

1. Default go metrics:

• Goroutines and Threads: go_goroutines (current number of goroutines) and go_threads (number of OS threads).
• Garbage Collection: go_gc_* provides a summary/histogram of GC internals.
• Go Environment: go_info gives details about the Go version.
• Memory Statistics (Memstats): A comprehensive set of metrics tracking memory allocation and usage, including go_memstats_alloc_bytes

2. Custom yproxy metrics:

Category	Name	Type	Description
Connections	client_connections	gauge	The number of client (yezzey) connections to yproxy
	external_connections_backup	gauge	The number of external yproxy connections to S3 backup storage
	external_connections_yezzey	gauge	The number of external yproxy connections to S3 yezzey storage
Requests	read_req_processed_total	counter	The total number of processed read (download) requests to S3 storage
	read_req_errors_total	counter	The total number of errors occurred while processing read requests
	write_req_processed_total	counter	The total number of processed write (upload) requests to S3 storage
	write_req_errors_total	counter	The total number of errors occurred while processing write requests
Internal	request_latency_bucket	histogram	The number of requests and requests time for each source request
	request_size_bucket	histogram	The number of requests and requests size for each source request

Internal metrics show latency and size for each source request. Source request is the internal type of query from GP to yproxy. Yproxy performs mostly upload/download requests to S3. But yezzey perform requests multiple species. They are named as source request. We measure source requests:

READ
WRITE
LIMIT_READ
LIMIT_WRITE
S3_PUT
S3_GET
CAT
CATV2
PUT
PUTV2
PUTV3
DELETE
LIST
LISTV2
OBJECT META
COPY
COPYV2
GOOL
ERROR
UNTRASHIFY
COLLECT OBSOLETE
DELETE OBSOLETE

Example of gathered metrics for a simple yezzey query:

query:
test=# select count(*) from public.ydt_100m;
   count
-----------
 100000000
