SNMP Configuration Full Monitoring

-
When you have monitoring system in place for the Linux environment, if you want to make a full use of it, you need to consider using SNMP protocol.

Net-SNMP needs to be installed in your Linux boxes and be configured properly.

Installation:

SNMP can be installed via yum command on Redhat/CentOS or "zypper" command in Suse servers:

# yum install net-snmp.x86_64


SNMP MIBs

With standard SNMP configuration, you don't get much details monitoring information you would like to have. So SNMP needs to be configured properly to produce all sort of SNMP MIBS.

A standard Linux SNMP config produce following limited MIBs only if we snmpwalk on it:

While for making full use of SNMP power, the config should lead to produce following loads of MIBs:(around 130 pages! showing only first 2 pages below)

Configuration

Following changes need to be done in a standard snmpd.conf file to make it produce all monitoring details. 

# vim /etc/snmp/snmpd.conf


In the following section, comment out first 2 lines started with "view"and add the third line to your config file:

  # Make at least  snmpwalk -v 1 localhost -c public system fast again.
  #     name        incl/excl   subtree       mask(optional)
--> comment out #view    systemview    included   .1.3.6.1.2.1.1
--> comment out #view    systemview    included   .1.3.6.1.2.1.25.1.1
--> Add view         all        included     .1            80

Before:
view    systemview    included   .1.3.6.1.2.1.1
view    systemview    included   .1.3.6.1.2.1.25.1.1

After:
#view    systemview    included   .1.3.6.1.2.1.1
#view    systemview    included   .1.3.6.1.2.1.25.1.1
view         all        included     .1            80


And in the following section, change the "systemview" to "all" in the line starts with "access":

  ####
  # Finally, grant the group read-only access to the systemview view.
  #  group   context sec.model sec.level prefix read   write  notif
--> access  notConfigGroup ""   any    noauth   exact  all none none

Before:
access  notConfigGroup ""  any  noauth  exact systemview none none

After:
access  notConfigGroup ""  any  noauth  exact all none none
and finally restart the snmpd daemon for new changes to take effect:

# /etc/init.d/snmpd restart 
Stopping snmpd:                                      [  OK  ]
Starting snmpd:                                      [  OK  ]

    What's pros and cons of this network monitor? I'm using total network monitor and never tried solarwinds solution. I need something for Server management on Linux.

    These days, specially for cloud monitoring, you should consider Datadog, a SaaS monitoring solution.

Linux and AIX user non expiry and force password change at first login

-
In Linux, if you want to set the password for an account to never expire, here is the command: # chage -I -1 -m 0 -M 99999 -E -1 username  And to force a user to change his password upon first login: # chage -d0 username Current status of the account can be checked via chage command : # chage -l username  Last password change                                    : Jun 18, 2013 Password expires                                        : never Password inactive                                       : never Account expires                                         : never Minimum number of days between password change          : 0 Maximum number of days between password change          : 99999 Number of days of warning before password expires       : 7 For AIX, to set the password to non expiry and force the user to change his password upon first login: # chuser expires=0 maxage=0 username  To check the username status in AIX: # lsuser -f username

Rebuild your new Yum repository after changing the packages

-
If you have done any  changes  to your local  repository  packages, adding new ones or deleting some, you can just simply update your yum sqlite metadata database for your changes to take effect, rather than creating the whole repository again which takes time if you have  thousands  of packages in your repository.  Here is how we rebuild our yum repository. 1. After you are done with adding/removing packages to your local repo, then: # createrepo --update /path/to/repo_dir 2. On the  client  side, you need to clean up the cached yum meta data in order to see the changes after repo rebuild: # yum clean all 3. Now update the  client  yum cache  # yum update

Running Docker Wildfly/JBoss Application Server in Debug mode via Eclipse

-
I have recently built the whole Development Environment of Java Enterprise Edition (J2EE) project on multiple Docker containers. It has saved the hassle of setting up a dev env for new developers. All it takes to setup the environment is to clone our github repositories and run the Docker images. I will explain the setup in a future post. Build Wildfly Docker Image with Debugging Enabled So basically in order to run the Wildfly in debug mode, we need to add --debug  flag to the Wildfly standalone.sh  startup script. Also we need to expose port 8787  in our image as it's the default port for Wildfly JVM debug mode. 1. Create or change your Wildfly Dockerfile as follows: $ cat Dockerfile FROM jboss/wildfly: 10.0 . 0 .Final EXPOSE 8787 CMD [ "/opt/jboss/wildfly/bin/standalone.sh" , "-b" , "0.0.0.0" , "-bmanagement" , "0.0.0.0" , "--debug" ] 2. Build and tag the image: $ docker build -t wildfly-debug . 3.
