@lnsh
Hi, could you post more detail here, such as your lua code, nginx config file and logs. Beside, how to judge it does not work?
[root@nginx01 script]# for uptream in grep upstream /usr/local/openresty/nginx/conf/upstream.conf | awk '{print $2}'; do echo $uptream; done | wc -l
104
local ok, err = hc.spawn_checker{
shm = 'healthcheck', -- defined by 'lua_shared_dict'
upstream = ...
type = 'http',
http_req = 'GET /status HTTP/1.0\r\nHost: healthcheck.nxin.com\r\n\r\n',
-- raw HTTP request for checking
interval = 2000, -- run the check cycle every 2 sec
timeout = 1000, -- 1 sec is the timeout for network operations
fall = 3, -- # of successive failures before turning a peer down
rise = 2, -- # of successive successes before turning a peer up
valid_statuses = {200, 302, 301,401,402,403, 404}, -- a list valid HTTP status code
concurrency = 10, -- concurrency level for test requests
}
...

local ok, err = hc.spawn_checker{
shm = 'healthcheck', -- defined by 'lua_shared_dict'
upstream = ...
type = 'http',
http_req = 'GET /status HTTP/1.0\r\nHost: healthcheck.nxin.com\r\n\r\n',
-- raw HTTP request for checking
interval = 2000, -- run the check cycle every 2 sec
timeout = 1000, -- 1 sec is the timeout for network operations

rise = 2, -- # of successive successes before turning a peer up
valid_statuses = {200, 302, 301,401,402,403, 404}, -- a list valid HTTP status code
concurrency = 10, -- concurrency level for test requests
}
if not ok then
ngx.log(ngx.ERR, "failed to spawn health checker: ", err)
return
end
}
upstream ,can not get requests
delete about 20 upstreams either from head or tail it works
openresty1.13.6
also update 1.15.8 test, the same problem
Hi, have you get some log in your error log? And could you post them here.
Maybe you can set your lua_max_running_timers and lua_max_pending_timers bigger and try, I think maybe there is some limit in the timer of nginx.
No error log
I try set lua_max_running_timers and lua_max_pending_timers , thx
Unluckily, it does not work too, conf like this
lua_max_pending_timers 2048;
lua_max_running_timers 1024;
log:
init_worker_by_lua error: init_worker_by_lua:1688: main function has more than 200 local variables
delete local it works, 3q
