我这里尝试pmacct V1.7.8+ndpi V4.4+elastiflow V6.4.3进行L7应用层流量统计，在启动pmacct V1.7.8后，我同样遇见了“nDPI support for fragmented traffic not implemented”的问题，这时我找到了[https://github.com/pmacct/pmacct/issues/428遇见了同样的问题，但似乎并未给出解决方案，之后在https://www.elastiflow.com/blog/posts/building-pmacct-with-ndpi-on-macos这篇帖子中的图片中发现能够正常分析应用流量，这是pmacct的问题，还是elastiflow版本的问题](https://github.com/pmacct/pmacct/issues/428%E9%81%87%E8%A7%81%E4%BA%86%E5%90%8C%E6%A0%B7%E7%9A%84%E9%97%AE%E9%A2%98%EF%BC%8C%E4%BD%86%E4%BC%BC%E4%B9%8E%E5%B9%B6%E6%9C%AA%E7%BB%99%E5%87%BA%E8%A7%A3%E5%86%B3%E6%96%B9%E6%A1%88%EF%BC%8C%E4%B9%8B%E5%90%8E%E5%9C%A8https://www.elastiflow.com/blog/posts/building-pmacct-with-ndpi-on-macos%E8%BF%99%E7%AF%87%E5%B8%96%E5%AD%90%E4%B8%AD%E7%9A%84%E5%9B%BE%E7%89%87%E4%B8%AD%E5%8F%91%E7%8E%B0%E8%83%BD%E5%A4%9F%E6%AD%A3%E5%B8%B8%E5%88%86%E6%9E%90%E5%BA%94%E7%94%A8%E6%B5%81%E9%87%8F%EF%BC%8C%E8%BF%99%E6%98%AFpmacct%E7%9A%84%E9%97%AE%E9%A2%98%EF%BC%8C%E8%BF%98%E6%98%AFelastiflow%E7%89%88%E6%9C%AC%E7%9A%84%E9%97%AE%E9%A2%98)

I see two older reports of a similar issue and it seems to be an issue with pmacct, or perhaps it is vendor related. Here a couple of old links reporting the issue, but I do not see any resolution.
