Junos OS

Hi,

Model: mx5-t
JUNOS Base OS boot [12.3R8.7]

Too many SNMP events seen in MX10,

SNMPD_HEALTH_MON_THRESH_CROSS: Health Monitor: RE 0 CPU utilization crossed rising threshold 80 (value: 100), (variable: jnxOperatingCPU.9.1.0.0

But when "show chassis routing-engine" command is applied the RE CPU is 91% idle.

show chassis routing-engine no-forwarding

Routing Engine status:
Temperature 34 degrees C / 93 degrees F
CPU temperature 44 degrees C / 111 degrees F
DRAM 2048 MB (2048 MB installed)
Memory utilization 28 percent
CPU utilization:
User 2 percent
Background 0 percent
Kernel 7 percent
Interrupt 0 percent
Idle 91 percent

"show system processes extensive" command output

show system processes extensive no-forwarding

last pid: 34811; load averages: 0.54, 0.26, 0.13 up 21+21:44:12 09:50:53
139 processes: 3 running, 108 sleeping, 28 waiting

Mem: 369M Active, 61M Inact, 77M Wired, 153M Cache, 112M Buf, 1327M Free
Swap: 2837M Total, 2837M Free

PID USERNAME THR PRI NICE SIZE RES STATE TIME WCPU COMMAND
11 root 1 171 52 0K 16K RUN 488.7H  70.31% idle
34768 root 1 113 0 35244K 25148K select 0:00  14.86% cli
34769 root 1 115 0 40204K 4124K select 0:00    5.13% mgd

I repeatedly captured the above 2 commands but no where noticed that CPU load is high, am suspecting it as a os bug, any advice would be helpful.

Thanks,

Chahd

Have you had this only on your MX5 ? becasue you also mention an MX10 in your post.

You could also check wether the device in question was monitored by SNMP and check for other values besides the CPU-utilization that changed during this period of time.

To cast a wider net one could check on the neighboring devices wether any events occured on these when the issue started ...

hope this give some hand

typo...just MX5.
