How can I monitor Disk Used% and Mem USed%

if Disk Used% is greater than HWM DISK% alarm

if Mem USed% is greater than HWM Mem% alarm

The asadm tool isn’t intended to be used for alerting, I suggest using a tool intended for alerting:

I have a zabbix monitoring system, I was just thinking about how to get Disk Used% and Mem Used%

Now I set up receiving parameters like this `sudo asadm -e info | grep -w "$namespace" | grep $node | awk 'NR == 1 {print $ 12}'`

I thought maybe there is a better option

These metrics are straight from the statistics command - the zabbix plugin can query them. See [https://www.aerospike.com/docs/reference/metrics/#device\_free\_pct](https://www.aerospike.com/docs/reference/metrics/#device_free_pct).

something the data somehow diverges

```auto
asadm -e info

puh aerospike2.:3000 1.547 B (1.198 B, 0.000) false 2.760 TB 48 80 33 190.429 GB 60 90 9
pus aerospike2.:3000 36.093 M (0.000, 548.121 K) false N/E N/E 50 N/E 19.205 GB 65 96 98

```

```auto
./aerospike_discovery.py -h aerospike2 -n puh | grep -A 1 -E "(device_free_pct|memory_free_pct)"

    "{#METRICNAME}":"memory_free_pct",
    "{#METRICVALUE}":"40"
    --
    "{#METRICNAME}":"device_free_pct",
    "{#METRICVALUE}":"52"

```

```auto
./aerospike_discovery.py -h aerospike2 -n pus | grep -A 1 -E "(device_free_pct|memory_free_pct)"

    "{#METRICNAME}":"memory_free_pct",
    "{#METRICVALUE}":"36"

```

through _asadm - e info_ I see for puh for Disk Used% - 29, HWM Disk% - 90, i.e. free should be 90 - 29 = 61, and the _aerospike\_discovery.py_ script shows device\_free\_pct - 52, also with memory, for pus Mem Used% - 65, HWM Used% - 96, 96 - 65 = 26, and _aerospike\_discovery.py_ memory\_free\_pct - 36

Am I misunderstanding something?

</div>

No, we wouldn’t compute as HWM% - USED%, it would be 100% - USED%.

These metrics aren’t computed on the client, they come from the server, for example, here is how device\_free\_pct is computed: [aerospike-server/thr\_info.c at master · aerospike/aerospike-server · GitHub](https://github.com/aerospike/aerospike-server/blob/master/as/src/base/thr_info.c#L5168).

That said, could you provide the full output from asadm - the snippet you provided is difficult to read without the header.

thanks for the help, made such checks

```
./aerospike_discovery.py -h $1 -n $2 | grep -A 1 "device_free_pct" | grep -v "#METRICNAME" | cut -d: -f2 | tr -d "\" "
./aerospike_discovery.py -h $1 -n $2 | grep -A 1 "memory_free_pct" | grep -v "#METRICNAME" | cut -d: -f2 | tr -d "\" "

```

just need to substitute your variables $1 - node, $2 - namespace
