我正在使用 MRTG,并将其配置为使用 RRD 记录性能数据(这是一个交换机接口字节计数器)。当我使用“rrdtool info”检查 RRD 文件时,我看到 ds[ds0].last_ds 是一个数字,每次输入新数据时它都会改变
# rrdtool info 10.0.3.129_24_bw.rrd
filename = "10.0.3.129_24_bw.rrd"
rrd_version = "0003"
step = 60
last_update = 1482950882
header_size = 2912
ds[ds0].index = 0
ds[ds0].type = "COUNTER"
ds[ds0].minimal_heartbeat = 600
ds[ds0].min = 0.0000000000e+00
ds[ds0].max = 1.2500000000e+08
ds[ds0].last_ds = "6332648954"
ds[ds0].value = 3.5016393443e+01
ds[ds0].unknown_sec = 0
ds[ds1].index = 1
ds[ds1].type = "COUNTER"
ds[ds1].minimal_heartbeat = 600
ds[ds1].min = 0.0000000000e+00
ds[ds1].max = 1.2500000000e+08
ds[ds1].last_ds = "32104385407"
ds[ds1].value = 5.3344262295e+01
ds[ds1].unknown_sec = 0
究竟是什么?谢谢!
