I’m going to use the Spring’s Actuator endpoint on /no-auth/actuator/info to parse the date of the last service’s git commit
and print a simple report with the age or my services.
$ curl --location --request GET production.myhost.com/myservice/no-auth/actuator/info|jq
returns
{
"git": {
"branch": "main",
"commit": {
"id": "effd243",
"time": "20220704-1031"
}
},
"build": {
"artifact": "myservice",
"name": "myservice",
"time": "2022-07-04T13:31:22.477Z",
"version": "0.0.1-SNAPSHOT",
"group": "com.alros.myservice"
}
}
add jq -r '.git.commit.time' and the line will just return the commit time.
The date can be parsed with
date -jf '%Y%m%d-%H%M' +%s ${commit_time}
Extracting the info for a service will be
commit_time=`curl --location --request GET ${base_url}/${service}/no-auth/actuator/info 2>/dev/null|jq -r '.git.commit.time'`
now=`date +%s`
commit=`date -jf '%Y%m%d-%H%M' +%s ${commit_time}`
age=`echo "(${now}-${commit})/3600"|bc`
Then it’s simply a matter of iterating over multiple services
get_server_status() {
base_url='production.myhost.com'
for service in 'myservice1' 'myservice2' 'myservice3'
do
commit_time=`curl --location --request GET ${base_url}/${service}/no-auth/actuator/info 2>/dev/null|jq -r '.git.commit.time'`
now=`date +%s`
commit=`date -jf '%Y%m%d-%H%M' +%s ${commit_time}`
age=`echo "(${now}-${commit})/3600"|bc`
printf "%30s %s %s %s hours\n" ${service} ${commit_time} ${age}
done
}
Add a parameter to switch environment (base_url)
get_server_status() {
if [ -z "$1" ]; then base_url='production.myhost.com'
elif [ "$1" = 'development' ]; then base_url='development.myhost.com'
elif [ "$1" = 'staging' ]; then base_url='staging.myhost.com'
elif [ "$1" = 'production' ]; then base_url='production.myhost.com'
else echo 'valid options are development, staging, production' && return -1
fi
printf "for %s\n" ${base_url}
for service in 'myservice1' 'myservice2' 'myservice3'
do
commit_time=`curl --location --request GET ${base_url}/${service}/no-auth/actuator/info 2>/dev/null|jq -r '.git.commit.time'`
now=`date +%s`
commit=`date -jf '%Y%m%d-%H%M' +%s ${commit_time}`
age=`echo "(${now}-${commit})/3600"|bc`
printf "%30s %s %s %s hours\n" ${service} ${commit_time} ${age}
done
}
Final touch: a bit of visualization
get_server_status() {
if [ -z "$1" ]; then base_url='production.myhost.com'
elif [ "$1" = 'development' ]; then base_url='development.myhost.com'
elif [ "$1" = 'staging' ]; then base_url='staging.myhost.com'
elif [ "$1" = 'production' ]; then base_url='production.myhost.com'
else echo 'valid options are development, staging, production' && return -1
fi
printf "for %s\n" ${base_url}
for service in 'myservice1' 'myservice2' 'myservice3'
do
commit_time=`curl --location --request GET ${base_url}/${service}/no-auth/actuator/info 2>/dev/null|jq -r '.git.commit.time'`
now=`date +%s`
commit=`date -jf '%Y%m%d-%H%M' +%s ${commit_time}`
age=`echo "(${now}-${commit})/3600"|bc`
if [ $age -lt 4 ]; then emoji='🐣'
elif [ $age -lt 24 ]; then emoji='🐥'
elif [ $age -lt 168 ]; then emoji='🐓'
else emoji='🍗'
fi
printf "%30s %s %s %s hours\n" ${service} ${emoji} ${commit_time} ${age}
done
}
output:
