High CPU usage on Juniper EX4300 virtual chassis

trouble with (all) junos device - they have troubles with snmpwalk of whole ifTable oid. And this issue very related to firmware version.

yep, you can make poller debug with this device_id (but this not make sense for issue, since you revert firmware version):

./poller.php -d -r -h 19

mysql> SELECT `device_id` FROM `devices` WHERE `disabled` = 0 AND `hostname` LIKE 'ex4300-vc.mngmt.pardubice.cmnet.cz' AND `poller_id` = '0' ORDER BY `device_id` ASC;
-----------
| device_id |
-----------
|        19 |
-----------
1 row in set (0.00 sec)

Please go to page: device -> performance data
and make screenshot of page.

still not:

SQL[SELECT `device_id` FROM `devices` WHERE `disabled` = 0 AND `hostname` LIKE 'ex4300-vc.mngmt.pardubice.cmnet.cz' AND `poller_id` = '0' ORDER BY `device_id` ASC]

show me device page in observium.

Attached poller/discovery is incorrect. You should use exactly same hostname for device as stored in observium or device_id. You always can see device_id in device page url.

General questions and device support can be discussed in our Discord channel, click here to join.

Please make and attach additional information about the device:

• full snmp dump from device:

  snmpwalk -v2c -c <community> -t 3 -Cc --hexOutputLength=0 -Ih -ObentxU <hostname> .1 > myagent.snmpwalk

  snmpwalk -v2c -c <community> -t 3 -Cc --hexOutputLength=0 -Ih -ObentxU <hostname> .1.3.6.1.4.1 >> myagent.snmpwalk

  If device not support SNMP version 2c, replace -v2c with -v1.

• If you have problems with discovery or poller processes, please do and attach these debugs:

  ./discovery.php -d -h <device>

  ./poller.php -d -h <device>

• additionally attach device and/or vendor specific MIB files
