How do I monitor Zimbra server with Grafana and InfluxDB?. This monitoring has bee done on an all in one Zimbra server deployment, but the setup is similar for other Zimbra installations. We assume you have already installed Zimbra Server or any other version before proceeding. If not, check Zimbra guides:

― Rumi
Step 1: Install InfluxDB
Install InfluxDB using our guides below.
Install InfluxDB on Ubuntu and Debian
Step 2: Configure influxdb
Open influxdb configuration file.
sudo vim /etc/influxdb/influxdb.confSet like below:
# Uncomment line 15
bind-address = "127.0.0.1:8088"
# On line 247 under http, uncomment it if you need http authentication
[http]
# Determines whether HTTP endpoint is enabled.
enabled = true
# On line 256, make sure that:
bind-address = ":8086"
Enable ports on firewall
# CentOS 7
sudo firewall-cmd --add-port=8086/tcp --permanent
sudo firewall-cmd --reload
# Ubuntu
sudo ufw allow 8086/tcpStep 3: Install Telegraf
Since the repository has been added already, just install telegraf
# CentOS
sudo yum -y install telegraf
# Ubuntu
sudo apt-get -y install telegraf
Follow this article covering installation of Telegraph on RHEL 8/ Centos 8:
A comprehensive guide on how to install Telegraph on Centos 7 is on our blog. Visit:
Step 4: Configure Telegraf
Use your favorite text editor to modify Telegraf configuration file.
sudo vim /etc/telegraf/telegraf.confSet to look like this:
[global_tags]
# Configuration for telegraf agent
[agent]
interval = "10s"
debug = false
hostname = "server-hostname"
round_interval = true
flush_interval = "10s"
flush_jitter = "0s"
collection_jitter = "0s"
metric_batch_size = 1000
metric_buffer_limit = 10000
quiet = false
logfile = ""
omit_hostname = false
###########################################################
# OUTPUTS #
###########################################################
[[outputs.influxdb]]
urls = ["http://influxdb-ip:8086"] # Input valid InfluxDB URL, IP address, and port
database = "database-name" # Input InfluxDB database name for this host
timeout = "0s"
username = "auth-username" # Input InfluxDB http authentication username.
password = "auth-password" # Input InfluxDB http authentication password.
retention_policy = ""
Create Zimbra specific telegraf file with inputs for Zimbra Processes, Zimbra Scripts, and Linux System Monitoring:
sudo vim /etc/telegraf.d/zimbra.confPaste below contents into the file:
# Read metrics about cpu usage
[[inputs.cpu]]
percpu = true
totalcpu = true
fielddrop = ["time_*"]
# Read metrics about disk usage by mount point
[[inputs.disk]]
ignore_fs = ["tmpfs", "devtmpfs"]
[[inputs.diskio]]
[[inputs.kernel]]
[[inputs.mem]]
[[inputs.processes]]
[[inputs.swap]]
[[inputs.system]]
[[inputs.procstat]]
exe = "memcached"
prefix = "memcached"
[[inputs.procstat]]
exe = "java"
prefix = "java"
[[inputs.procstat]]
exe = "mysqld"
prefix = "mysqld"
[[inputs.procstat]]
exe = "slapd"
prefix = "slapd"
[[inputs.procstat]]
exe = "nginx"
prefix = "nginx"
[[inputs.net]]
[[inputs.exec]]
commands = ["/opt/zimbra/common/bin/checkzimbraversion.sh"]
name_override = "zimbra_stats"
data_format = "value"
data_type = "string"
# # OpenLDAP cn=Monitor plugin
# # As zimbra user run the next to obatin the password zmlocalconfig -s zimbra_ldap_password ldap_master_url
[[inputs.openldap]]
host = "YOURZIMBRASERVERHOSTNAME"
port = 389
insecure_skip_verify = true
bind_dn = "uid=zimbra,cn=admins,cn=zimbra"
bind_password = "YOURZIMBRALDAPPASSWORD"
reverse_metric_names = true
[[inputs.postfix]]
queue_directory = "/opt/zimbra/data/postfix/spool"
interval = "1s"
Update the following values correctly:
- YOURZIMBRASERVERHOSTNAME – With your Zimbra server hostname
- YOURZIMBRALDAPPASSWORD – With Zimbra LDAP Password
Create the script to check Zimbra version:
$ sudo vim /opt/zimbra/common/bin/checkzimbraversion.sh
#!/bin/bash
if [ -f /etc/redhat-release ]; then
rpm -q --queryformat "%{version}" zimbra-core | awk -F. '{print $1"."$2"."$3 }' | awk -F_ '{print $1" "$2 }'
fi
if [ -f /etc/lsb-release ]; then
dpkg -s zimbra-core | awk -F"[ ',]+" '/Version:/{print $2}' | awk -F. '{print $1"."$2"."$3" "$4}'
fiMake the script executable
sudo chmod a+x /opt/zimbra/common/bin/checkzimbraversion.shOnce done, restart telegraf service
sudo systemctl restart telegrafStep 5: Install Grafana Monitoring Tool
Install Grafana server on your server:
The default HTTP port is 3000, and default user and group is admin.
Add the port to firewall..
# CentOS 7
sudo firewall-cmd --add-port=3000/tcp --permanent
sudo firewall-cmd --reload
# Ubuntu
sudo ufw allow 3000/tcpOnce done, head over to http://ip-address:3000
Username: admin
Password: adminReset the password after initial login.
Step 6: Import Data Sources
Login to Grafana and Add InfluxDB data source
Click on InfluxDB
On the above screen, input any name and on the InfluxDB Details, input the database as specified in telegraf.conf file, and username and password as well from the same file.
Yous should see a message in green as shown above. After that is done, we can import a dashboard. This dashboard was created by Jorge de la Cruz (jorgedelacruz.es) and all credit goes to him.
Head over to Here to view it. Otherwise, you can just put 2846 as the dashboard id and click on load.
You should see a dashboard as shown below:
