NTP server stats - dreamstation.systems ======================================= we run two time servers. dreamstation.systems is a member of pool.ntp.org, serving time on UDP/123 (plain NTP) and TCP/4460 (NTS). starport.dreamstation.systems serves time on UDP/123 (plain NTP), and gets its own time from dreamstation over NTS. these are some live stats for both, regenerated every 5 minutes from each box's chronyd and a standing nftables packet counter. right now --------- dreamstation starport ------------ -------- queries/second 9.9k 6.6k 30-minute average 8.7k 6.4k 24-hour average 8.5k 6.4k 7-day average 8.4k 6.2k bandwidth serving time 737.8 KiB/s 495.6 KiB/s 24-hour average 633.3 KiB/s 478.0 KiB/s clients rate-limited 5.8% 0.3% 30-minute average 5.9% 0.3% our stratum 2 3 syncing to ntp.your.org dreamstation.systems rms clock offset 10 microsec 105 microsec averages cover only as much history as a server has: dreamstation: 7.0 days of samples starport: 7.0 days of samples queries per second, last 24 hours (UTC) --------------------------------------- dreamstation starport 13:00 |#################### 8.6k |################### 6.4k 14:00 |#################### 8.7k |################### 6.6k 15:00 |#################### 8.8k |#################### 6.6k 16:00 |#################### 8.9k |#################### 6.8k 17:00 |##################### 9.1k |#################### 6.9k 18:00 |##################### 9.0k |#################### 6.9k 19:00 |#################### 8.8k |#################### 6.9k 20:00 |#################### 8.8k |##################### 7.1k 21:00 |##################### 9.0k |#################### 6.9k 22:00 |#################### 8.6k |################### 6.6k 23:00 |##################### 9.2k |#################### 6.8k 00:00 |##################### 9.1k |##################### 7.1k 01:00 |################### 8.4k |################### 6.5k 02:00 |#################### 8.6k |################### 6.5k 03:00 |#################### 8.6k |################### 6.4k 04:00 |################## 7.9k |################## 6.1k 05:00 |################### 8.2k |################## 6.1k 06:00 |################## 7.8k |################## 5.9k 07:00 |################## 7.9k |################# 5.7k 08:00 |################## 8.0k |################# 5.8k 09:00 |################## 7.8k |################# 5.7k 10:00 |################## 8.0k |################# 5.7k 11:00 |################### 8.3k |################### 6.3k 12:00 |#################### 8.7k |################### 6.4k each column is scaled to its own peak.
