Hello,
I am trying to monitor some service (httpd, ssh) / process through Linux SNMP monitoring
But, seeing below error. Please help me to understand what I am missing here

For the host that is being monitored, can you please post the /etc/snmp/snmpd.conf file.

Process checks.
#
The following are examples of how to use the agent to check for
processes running on the host. The syntax looks something like:
#
proc NAME [MAX=0] [MIN=0]
#
NAME: the name of the process to check for. It must match
exactly (ie, http will not find httpd processes).
MAX: the maximum number allowed to be running. Defaults to 0.
MIN: the minimum number to be running. Defaults to 0.
#
Examples (commented out by default):
#
Make sure java is running
proc java
make sure nmbd is also running
#proc nmbd
proc mysqld_safe [MAX=1] [MIN=1]

disk checks
#
The agent can check the amount of available disk space, and make
sure it is above a set limit.
disk PATH [MIN=100000]
#
PATH: mount path to the disk in question.
MIN: Disks with space below this value will have the Mib's errorFlag set.
Default value = 100000.
Check the / partition and make sure it contains at least 10 megs.

time, the errorFlag will be set.
5MAX: Similar, but for 5 min average.

So you have a restrictive config which is preventing certain OID's from being returned.
In your /etc/snmp/snmpd.conf, this line will relax the restrictions, add it at about line 53
Then restart snmpd
Now it should work for you.
